Abaqus/Explicit: Dynamic failure models
Abaqus/Explicit: Dynamic failure models
(OP)
There are two simple models for Dynamic failure, TENSILE FAILURE and SHEAR FAILURE - http://abaqus.ethz.ch:2080/v6.14/books/usb/default...
So far what I understood, with element deletion ON -
*TENSILE FAILURE, ELEMENT DELETION=YES
[hydrostatic cutoff stress]
*SHEAR FAILURE, ELEMENT DELETION=YES
[equivalent plastic strain at failure]
My question is, how do I determine the hydrostatic cutoff stress parameter from a uni-axial tensile stress-strain data? The equivalent plastic strain at failure can be found as (Total strain - Elastic strain), right?
