I want to simulate the bulging of a circular thin steel plate due to fluid pressure and finally see the rupturing of it.
What is the best criteria to simulate the material properties in plasticity and damage for this type of problem in Abaqus software.
Material is SS316 or something like that which we have the uniaxial tensile test results. And has a 1mm thickness and 100mm diameter.
Loading is a simple progressive uniform pressure.
Thanks
Hi, This depends on the material response, i.e. the Stress - strain curve. If the material hardened after the yield, Hardening material properties should be considered, i.e. this depend in the slope of the curve after yielding however, elastic-perfectly plastic is most common in analysing to be safer for the design purpose.
Best wishes.
