Create a crack on 2D plate using ABAQUS, looking for the stress intensity factor

Submitted by eayaktw on

Hi all,

I am a new user to ABAQUS, and, i am trying to create a crack on a 2D plate by using ABAQUS, and hence look for the stress intensity factor(material: PMMA)

However, i really dun know wut to do after i have created the part (set up the coordinate). 

Could anyone please give me the procedure? (PLZ, PLZ, PLZ) 

Thank you very much.

PDF position at the University of New Brunswick, Canada

Submitted by Zengtao Chen on

A post-doctoral position is available in the area of material modeling of composite at the University of New Brunswick, Fredericton, Canada. Particularly, expertise is sought in finite element simulation of damage/fracture and thermomechanical properties of fiber composite. Experience in multiscale finite element modeling of fracture and damage behavior of composite materials is required.

ANSYS

Submitted by r.a.alashti on

Dear all,

Hello, I am working on stress analysis of a plate by ANSYS, I need to change material properties and real constants of some elements while the load is increased say from load step 1 to 1.1 and onwards. By using restart command the program either restart the analysis from zero loading with new values of MT and RC for the elements or keep the substeps of the load and does not change the MT and RCs.

Please note that the selected element does not support "kill" command.

Dynamic fracture toughness of PMMA decreases with crack velocity

Submitted by chaumcor on

Dear Alls;

I am loking for the paper which said the Dynamic fracture toughness of PMMA decreases with crack velocity under impact loading, but after crack starts propagation, crack velocity is a decreasing function with crack propagation length.

So, if you know the paper which related to that problem, Could you please show me its title?

 

Thank you very much,

Best Regards,
