compressive strength from ansys model
hi,
is it possible to find the compressive strength of brick, from finite element model, using ansys. if so, please explain the procedure.
thank you
how to verify the UEL result of ABAQUS
how to verify the UEL result of ABAQUS？
can i get the information of some node,such as displacement ,strain ,and so on . how to get ? where to get ? some fortran code should written in UEL?
thanks in andvance!
Communication between Matlab and Nastran
Hi All,
Could you please tell me how I can make communication between Matlab and Nastran? Actually I want to send some force data from Simulink to a deformable object in Nastran and then I will read the deformation of the object in Simulink. After that I will recalculate the forces and send it back to Nastran till some desired criteria is made. Can anybody help me to figure out this? Could you please pass it to me if you have any source code?
Thanks in advance

R C Beams
I am a novice user of abaqus and trying to model crack growth in rc beams with longitudinal reinforcement and stirrups under dynamic loads by try and error method
rebar layers are in shell element and i am using CDP for my concrete. i am trying to find out if i need to have many solid parts or one is enough and if mesh adaptivity is necessary or not because of crack growth . I appreciate any consulting in this field and i will share my knowledge with anybody that helps me
my first error message is
New methods of analyzing indentation experiments on very thin films
Abstract - Indentation experiments on very thin films are analyzed by employing a rigorous solution to model elastic substrate effects. Two cases are discussed: elastic indentations where film and substrate are anisotropic, and elasto-plastic indentations where significant material pile-up occurs. We demonstrate that the elastic modulus of a thin film can be accurately measured in both cases, even if there is significant elastic mismatch between film and substrate.

Consistent linearized tangent moduli for hyperelastic materials... is it always a positive definite matrix?
In order to obtain numerical solution of problemsthat involves a hyperelastic material model, we use what is known as incremental/iterative solution techniques of Newthon's type. The basic idea is to contruct a discrete system of nonlinear equation, KU=F, and solving it using a Newton's method or a modified version of it. As we know, its lead to a systematic linearization of the internal force vector and by the chain rule to the linearization of the material model.
