i study model with non stress strain curve how could i define it in ansys material (multi linear isotropic hardening)
📷
when calculate these values:
True Strain = ln(1+Strain) where ln is the natural logarithm function.
True Stress = Stress(1+Strain)
Elastic Strain = True Stress/E
Plastic Strain = True Strain - Elastic Strain
where:
fy=309 mpa
fu= 580 mpa
E= 210 gpa
i get:

but the deformation decreases from 0.006 to 0.001 and still solve linear i donot know what is the problem
Check your boundary condition and attach an engineering data material shot then we discuss about that
Hi there,
If you don't input stress-strain curve in Ansys, it means Ansys will define the result based on bilinear relationship. Do you apply similar element type for all models?
i have define trilinear stress strain curve using values indicating above but the total deformation decreased from 0.006 to 0.001
Check your boundary condition and attach an engineering data material shot then we discuss about that
