slight deviation in Abaqus stress-strain curve..need help
(OP)
How to overcome this problem?
While comparing Tensile Stress-Strain curve of Experimental and Abaqus results, slight deviation after yield stress found in Abaqus results.
-checked material data elastic and plastic
-Tried BC with velocity = 0.00833 mm/sec or displacement = 2 mm with smooth/equally spaced/tabular amplitudes. But the deviation exists.
-Step, Time period with auto or fixed parameter are tried. But still deviation exists.
