residual stress
[Abaqus]Residual Stress, Equlibrium step, Boundary conditions
Hello
Problem description: There is a simply supported(roller supports) shell element I-beam. There are lateral bracings too. All of this boundary conditions belongs to the Riks step(always last step in analysis).
Question: I have implemented triangular residual stresses by SIGINI subroutine, but I'm not sure what boundary conditions set up in preliminary equlibrium step. Should I include all of the lateral bracings in this step or maybe only roller support?
Thank You
residual stress and strain definitions (through-thickness) in ABAQUS/Explicit

Hello everyone,
I need some help regarding the definition of initial residual stresses and plastic strains in a shell finite element (S4R) model in ABAQUS/Explicit.
I have determined the residual stress distributions and initial plastic strains and I need to assign these distributions to a given element set.
I understand I should be looking at:

Fatigue Crack Growth Under Spectrum(Random) loading
Dear all Researchers,
I am writing regarding for the first time about the UAA(Unified analytical aspect) on Fatigue crack growth. The idea of this technique is this question : too many fatigue life prediction relations but still those are not perfect. on the other hand, new math ways still have not been the classical fracture mechanics. I am looking for some comments as response to this concern. Clearly, how we upgrade fracture mechanics theory using atomistic development in modeling fatigue propagation?
Let us talk about this.

Hello There,
Residual stress measurement
Hi Everyone,
I would like to measure the residual stress imposed pattern through thickness of the plate by forming process (bending). Is it possible?
I came to know that residual stress measurement through HOLE DRILLING METHOD offers only on the surface. That too, applicable only when residual stress imposed is uniform through thickness (like shot blasting process). If any one came across the experience of residual stress measurement, please throw some light in this regard.
Thanks in advance
