How to determine the Centre of rotation in Abaqus/CAE

Submitted by filutza on Tue, 07/28/2015 - 19:14

I need to determine the centre of rotation of the head of the femur and acetabular bones using Abaqus.
How can I find the centre of rotation for a sphere and a concave surface (the head of the femur and acetabulum bones) in Solid Edge?

Thank you.

Ductile crack modeling with XFEM and Damage criterion in Abaqus

Submitted by Brick chaouche Amine on Tue, 07/28/2015 - 14:24

Good mourning, i'll ask a quick and strightforward question abour Abaqus fracture analysis capabilities, in case of a crack in a ductile material, when one want to use arbitrary path crack propagation with XFEM, what's the suitable damage initiation criterion to use for this case?

Node rotation in UEL definition

Submitted by ashkan khalili on Tue, 07/28/2015 - 14:17

Hi everyone,

I'm working on UEL and recently I've developed a shell element. To define an element in input file, I'm using counter-clockwise rotation for nodes. When it's just one element everything is good.

exponential softening cohesive zone (ABAQUS)

Submitted by nour202 on Tue, 07/28/2015 - 13:52

Hi everyone,

what is the exponential curve used in ABAQUS to model the softening (damage evolution) for cohesive interaction? Reading the documentation, I find the equation for D (damage variable) in linear and exponential cases. But the exponetial curve is not given there (maybe it is not given explicitly).

Thanks,

Amir
