This textbook treats solids and fluids in a balanced manner, using thermodynamic restrictions on the relation between applied forces and material responses. This unified approach can be appreciated by engineers, physicists, and applied mathematicians with some background in engineering mechanics. It has many examples and about 150 exercises for students to practice. The higher mathematics needed for a complete understanding is provided in the early chapters. This subject is essential for engineers involved in experimental or numerical modeling of material behavior.

Fluid Dynamics: Theory, Computation, and Numerical Simulation
Constantine Pozrikidis
Springer English
2009-05-26
ISBN: 038795869X
774 pages
PDF 9,6 MB
Fluid Dynamics: Theory, Computation, and Numerical Simulation is the only available book that extends the classical field of fluid dynamics into the realm of scientific computing in a way that is both comprehensive and accessible to the beginner. The theory of fluid dynamics, and the implementation of solution procedures into numerical algorithms, are discussed hand-in-hand and with reference to computer programming. This book is an accessible introduction to theoretical and computational fluid dynamics (CFD), written from a modern perspective that unifies theory and numerical practice.
There are several additions and subject expansions in the Second Edition of Fluid Dynamics, including new Matlab and FORTRAN codes. Two distinguishing features of the discourse are: solution procedures and algorithms are developed immediately after problem formulations are presented, and numerical methods are introduced on a need-to-know basis and in increasing order of difficulty. Matlab codes are presented and discussed for a broad range of topics; from interfacial shapes in hydrostatics, to vortex dynamics, to Stokes flow, to turbulent flow.
A supplement to this book is the FORTRAN software library FDLIB, freely available through the Internet, whose programs explicitly illustrate how computational algorithms translate into computer code instructions. The codes of FDLIB range from introductory to advanced, and the problems considered span a broad range of applications; from laminar channel flows, to vortex flows, to flows in aerodynamics. Selected computer problems at the end of each section ask the student to run the programs for various flow conditions, and thereby study the effect of the various parameters determining each flow. FDLIB offers an extensive range of Fortran 77 and Matlab programs that demonstrate the implementation of elementary and advanced algorithms and provide an invaluable resource for research, classroom instruction, and self-study.
This text is a must for practitioners and students in all fields of engineering, computational physics, scientific computing, and applied mathematics. It can be used as a text in both undergraduate and graduate courses in fluid mechanics, aerodynamics, and computational fluid dynamics. The audience includes not only advanced undergraduate and entry-level graduate students, but also a broad class of scientists and engineers with a general interest in scientific computing.

Thanks a lot karla for starting this new topic.
I´d like to share an alternative for your Steel Shapes Blocks, using a LISP to drawing parametric 2D and 3D Shapes. This lisp is royalties free and originally posted in Cadalyst Magazine.
I tested in AutoCAD 2002 to 2008 and works well.
The Info: (same as STL_help.txt file inside):
COMPANION FILES:
^^^^^^^^^^^^^^^^^^^^^
STL.LSP HAS 22 COMPANION FILES THAT ARE REQUIRED TO BE IN THE SAME DIRECTORY IN ORDER TO FUNCTION. THESE FILES ARE NAMED AS FOLLOWS:
STL.DCL, STL_HELP.TXT, STL_C.DIM, STL_HP.DIM, STL_L.DIM, STL_M.DIM, STL_MC.DIM, STL_MET_A.DIM, STL_MET_C.DIM, STL_MET_R.DIM, STL_MET_W.DIM, STL_MT.DIM, STL_P.DIM, STL_PX.DIM, STL_PXX.DIM, STL_S.DIM, STL_ST.DIM, STL_TS_RECT.DIM, STL_TS_SQ.DIM, STL_TUBE.DIM, STL_W.DIM, STL_WT.DIM.
THESE FILES CONTAIN THE DIALOG (.DCL) CODE, THIS HELP FILE (.TXT) AND THE DATA TABLES FOR SHAPE DIMENSIONS (.DIM).
1. ABOUT THE PROGRAM:
^^^^^^^^^^^^^^^^^^^^^^^
A. ALL SHAPES ARE DRAWN AS POLY-LINES FOR EASE OF HANDLING, EXTENDING TO, TRIMMING TO, CHANGING LINETYPE OF, REGION MODELING FOR COMPOSITE SHAPE ANALYSIS, AND CONVERTING TO 3D SOLID AND 3D SIMPLE. INCLUDES AUTOMATIC "PLINEWID" SETTING TO "0", THEN RE-SET TO ORIGINAL SETTING.
B. INSERT POINTS ARE TOP BEAM CENTER, TOP TUBE CENTER, PIPE OR TUBE CENTER, ANGLE HEEL, AND CHANNEL HEEL.
C. SHAPE CONTOURS ARE DRAWN ACCURATELY WITH TAPERED FLANGES AND RADIUSED CORNERS AND EDGES.
D. THE PROGRAM SETS AN AUTOMATIC "OSMODE" SETTING OF "111" (INTERSECTION, ENDPOINT, MIDPOINT, CENTERPOINT, NODE, AND INSERTION) TO AID IN SELECTING INSERT POINT, AUTOMATIC RE-SET TO "0" FOR DRAWING THE SHAPE, THEN RESET TO ORIGINAL OSMODE OF DRAWING ENVIRONMENT.
E. INSERT PROMPT HAS A REFERENCE OPTION. THIS ALLOWS PLACEMENT OF INSERT POINT BY "PICKING" A BASE POINT AND THEN ENTERING ITS X,Y REFERENCE TO THE "PICKED" BASE POINT.
F. PROGRAM DRAWS ALL OF THE STRUCTURAL SHAPES, PIPE, AND TUBE LISTED IN THE AMERICAN INSTITUTE OF STEEL CONSTRUCTION'S (AISC) STEEL CONSTRUCTION MANUAL, EITHER THE ASD NINTH EDITION OR THE LRFD FIRST EDITION. METRIC SHAPE DATA TABLES WERE OBTAINED FROM BEAM.LSP BY STEVE Q. STAPLETON AND BILL LE COUTEUR.
G. THE PROGRAM ALTERS THE DRAWING ENVIRONMENT WITH A TEMPORARY "OSMODE" "111" AND "PLINEWID" "0" SETTING. SHAPES ARE DRAWN ON THE CURRENT LAYER AND UCS.
H. IF YOU MAKE IMPROVEMENTS, HAVE COMMENTS, OR FIND BUGS, PLEASE CONTACT ME BY E-MAIL: [email protected]
2. LOADING AND STARTING THE PROGRAM:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
A. FIRST, ALL STL FILES SHOULD BE LOCATED IN THE SAME DIRECTORY. THE DIRECTORY SHOULD BE SPECIFIED IN THE AUTOCAD SEARCH PATH. MY PERSONAL APPROACH IS TO PUT ALL MY CUSTOM AUTOLISP FILES IN A DIRECTORY CALLED AUTOLISP WHICH I THEN ADD TO MY AUTOCAD SEARCH PATH. THIS KEEPS THEM SEPARATE FROM ALL THE ONES SUPPLIED WITH AUTOCAD IN THE SUPPORT DIRECTORY.
B. LOADING CAN BE DONE BY VARIOUS MEANS DEPENDING ON HOW FREQUENTLY YOU EXPECT TO USE THE PROGRAM. FOR INFREQUENT USE, THE "LOAD APPLICATION" MENU ON THE "TOOLS" PULL-DOWN (R13 AND R14) MAY SUFFICE. YOU CAN ALSO LOAD DIRECTLY AT THE COMMAND PROMPT BY TYPING (LOAD "STL") AND PRESSING ENTER. FOR FREQUENT USERS WHO WANT THE PROGRAM AVAILABLE AT ALL TIMES, ADD (LOAD "STL") TO YOUR ACAD.LSP FILE SO THAT THE PROGRAM LOADS AUTOMATICALLY EVERY TIME. YOU CAN THEN START THE PROGRAM BY TYPING STL AT THE COMMAND PROMPT OR BY CONFIGURING A CUSTOM TOOLBAR BUTTON TO START. MY PERSONAL APPROACH IN R13 AND R14 IS TO CREATE AND CONFIGURE A CUSTOM TOOLBAR BUTTON THAT BOTH LOADS AND STARTS THE PROGRAM. THE BUTTON COMMAND IS (LOAD "STL") STL. IT'S THAT SIMPLE.
3. PICK THE SHAPE TYPE:
^^^^^^^^^^^^^^^^^^^^^^^^^
WHEN THE PROGRAM STARTS, IT CALLS UP THE MAIN DIALOG BOX. THE BOX CONTAINS 20 BUTTONS, ONE FOR EACH AVAILABLE SHAPE TYPE. WHEN A BUTTON IS SELECTED, A LIST OF AVAILABLE SHAPE SIZES IS DISPLAYED IN THE LIST BOX.
4. PICK THE SHAPE SIZE:
^^^^^^^^^^^^^^^^^^^^^^^^^
SCROLL THE LIST OF AVAILABLE SHAPE SIZES AND PICK A SIZE. THE PICKED SIZE WILL BE HIGHLIGHTED AND A LIST OF THE DIMENSIONS FOR THAT SIZE WILL BE DISPLAYED TO THE LEFT OF THE LIST BOX.
5. PICK THE VIEW:
^^^^^^^^^^^^^^^^^^^
FIVE VIEW SELECTIONS ARE AVAILABLE BY RADIO BUTTONS. SELECT A VIEW BUTTON AND YOU ARE NOW READY TO DRAW THE SHAPE. THE 2D END VIEW IS DEFAULT. IF YOU SELECT ANY OF THE OTHER 4 VIEWS, A LENGTH DIMENSION IS REQUIRED IN THE HIGHLIGHTED LENGTH EDIT BOX. IF YOU DO NOT ENTER A LENGTH DIMENSION THE DEFAULT IS 1 UNIT.
6. PICK OK:
^^^^^^^^^^^^^
THE PROGRAM WILL DISPLAY AN ALERT BOX WITH A OOPS! ERROR MESSAGE TO TRY AGAIN IF YOU FAIL TO PICK EITHER A SHAPE TYPE OR SHAPE SIZE. IF YOU FAIL TO SELECT A VIEW, THE PROGRAM WILL DRAW THE 2D END VIEW BY DEFAULT.

PDF 2.35 MB
Creep and fatigue are the most prevalent causes of rupture in superalloys, which are important materials for industrial usage, e.g. in engines and turbine blades in aerospace or in energy producing industries. As temperature increases, atom mobility becomes appreciable, affecting a number of metal and alloy properties. It is thus vital to find new characterization methods that allow an understanding of the fundamental physics of creep in these materials as well as in pure metals.
Here, the author shows how new in situ X-ray investigations and transmission electron microscope studies lead to novel explanations of high-temperature deformation and creep in pure metals, solid solutions and superalloys. This unique approach is the first to find unequivocal and quantitative expressions for the macroscopic deformation rate by means of three groups of parameters: substructural characteristics, physical material constants and external conditions.
Creep strength of the studied up-to-date single crystal superalloys is greatly increased over conventional polycrystalline superalloys.

It's a good idea open possibility to post interesting and curious links about structures (in general). I'm not referring a existing "Famous Projects" forum.
If yes, where is the best place?
The idea is put links like:
