The most suitable method to calculate the stress intensity factor in the presence of contact between the crack lips?

I'm trying to study cracked structures under a compressive load taking into account contact between the crack lips. I would like to know if the method of extrapolation by displacement remains...

Is there any effective FEM solver to perform simulation of balloon inflation with large deformation (e.g. 300% strain)?

Hi! Thank you for your time, attention, and support. I am currently using FEM solver Abaqus to perform a set of balloon inflation simulations, trying to understand the deformation shape, stress,...

Do we need to keep looking for the fracture angle after the Puck's failure initiation is reached?

Greetings to everyone, Our team is currently working on the development of a VUMAT code in Abaqus for composite modelling using the Puck's failure theory as damage initiation criteria. Currently...
