For the strength prediciton of composite plate which criterion can be used is it the maximum stress, maximum strain, principal stress or by using stress Invariants
I'm modeling rock fracture problem with cohesive element. I konw the propertiey of the solid element around the fracture because we can measure it (rock sample) in the lab. but as regard to how to define the propeties of cohesive element, I'm completely lost.
in fact, the cohseive element is a fictitious one, not a real matearial in the physical world, we can't mearsure its propety by physical means. then how can we know what parameters we should enter ?
need your help, thanks
How to model SMA wire embeded in composite beam using Abaqus using 3D solid extrusion?
The model is cantilever beam of composite in which the SMA wire is embeded in neutral axis of the beam.
I only simulate deflection.
The simulation without SMA has been succesfully done which show deflection when applied load at the tip( free end)

Hi, everyone.
I'm going to employ the meshfree method to analyze composite model.
But, I can't understand how to determine the support radius although I have read some references.
I will use the circular support domain.
Please explain how to determine the support radius.
Hi ,
I am trying to develop material model for cyclic loading by doing a cyclic loading test on a tention coupon.
It is a strain control test.The strain cycles of 10 cycles are applied at (2%,5%,6%,8%) rate.
The problem is that I want to apply this strain rate to the middle gauge length of tention coupon.
But in abaqus I can apply this load as a displacement load only at one end of tention coupon.
IS there any option is abaqus where I can change the displacement load at one end according to the strain variation in the gauge length
Hi!
I'm already simulating a shape memory alloy behavior with the aid of the HETVAL subroutine, but I'd like to use UMATHT instead, since the HETVAL can't simulate correctly heat absortion(cooling down).
I've tried to add the required values for UMATHT without achieving a correct phase fraction simulation, and some times even no compilation of the .for file.
Is there any other examples that uses UMATHT besides the Stefan problem?
Any other recommendation about HETVAL to UMATHT migration?
Thanks in advance!
Hello,
I'm trying create a bridge between scales using Abaqus, UMAT subroutine.
On macro scale I call UMAT, which calls other abaqus inp. with this example code
call SYSTEM('abaqus cae script=C:\Temp\mixUMAT\simpleModel.py -- A 2 5.3')
And my "simpleModel" receives all arguments properly.
However, I need some values which are calculcated on "simpleModel", to UMAT continues the executation.
Anyone knows how can I do it?
Thank you!
