Fracture Mechanics vs. Damage Mechanics
I was wondering what are the advantages of damage mechanics and fracture mechanics over each other? Specially in order to model the delamination phenomenon.
MECHANICAL ENGG&abaqus contact analysis
dear all,
this is arasu, i am using abaqus to find out wear using contact analysis.my model rotating disc over the pin(pin on disc ) in real time.so i want t o simulate rotating disc at some anular velocity.if any body have some solved problem about ratating geomentry please send me.
thank you
regards
Arasu
Reading elsets from UMAT in ABAQUS
Dear all,
I intend to read the element sets which I have in my Abaqus input file from the user material code (UMAT) and check to which elset the current element, which is characterized by "NOEL" in the UMAT, belongs.
Best,
Hadi
Looking for a postdoc on Laser Material Processing
I am already PhD candidate of Mechanical Engineering in Southern Methodist University, Dallas, Texas. I am looking for a postdoc position with an emphasis on laser material processing. You may access my CV by:
Failure Surface Graphics in Stress Space
A new section has been added to the website on failure criteria for engineering materials. This new work displays many different three-dimensional computer graphics of failure criteria surfaces in stress space. The full range of isotropic materials are covered from ductile metals to brittle ceramics and glasses and beyond. All of these computer generated graphics can be seen at www.failurecriteria.com/failuresurfacegr.html.
Prof. Ares Rosakis has been elected to a fellow of the American Academy of Arts and Sciences, 2009
Solid mechanician and Caltech Faculty Member Named to American Academy of Arts and Sciences: Caltech professor Ares Rosakis, is among the 210 new fellows elected to the American Academy of Arts and Sciences this year. They join an assembly that was founded in 1780 by John Adams, James Bowdoin, John Hancock, and other scholars to provide practical solutions to pressing issues.
Error Code 144
Hello all, new to the forum, so I would like to say thank you in advance for any help I may receive.
I have been using CPS8R elements to model a plane stress problem, in conjunction with a UMAT I have developed. This has been running correctly, and the results obtained are good.
I am now running an analysis using axisymmetric elements, CAX8R.
The output from CAX8R is..... S11, S22, S33, S12. The ouput from CPS8R is....S11, S22, S12.
I have therefore updated the damage model accordingly to account for this.
ANSYS FINITE ELEMENT ANALYSIS
While analysing through ANSYS We have to give the strees strain curve for fibre reinforced concrete. How stress strain curve for fibre reinforced concrete is given while analysis.I have tested compression stress on cylinder and have stress strain curve for compressive test on cylinder
