Dear everyone,

The third issue in 2015 (Volume 5, Issue 3) of Theoretical and Applied Mehcanic Letters (TAML) is now online.

Welcome to this OA journal http://taml.cstam.org.cn or http://www.sciencedirect.com/science/journal/20950349/5/3 for rapid publication of your exciting results.

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.

Dear researchers,

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?

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.

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

Hello,

My work is related to creep in ceramics. Often I find the relation between the creep strain rate and stress as:

creep_strain_rate = constant x stress x other_factors                  (1)
