Piecewise UMAT plastic Model
Posted: 03 Jan 2020, 12:10
Added a piecewise linear fit for the stress strain curve to provide a more general plastic material input.
constants are nu,x1,y1,x2,y2,...,xn,yn
results test case, the UMAT is in the zip with the test model
Number of material constants is (number of points*2)+1constants are nu,x1,y1,x2,y2,...,xn,yn
results test case, the UMAT is in the zip with the test model
