I done the simulation of loading and unloading of the structure with assigning the engineering data as isotropic table(youngs modulus and poisson ratio) and multilinear isotropic hardening (true stress vs plastic strain). I got the different result in unloading condition than experimental one. I studied about that the viscoelastic material while unloading it has permanent deformation is less compared to ductile material. I done the experiment of that structure which has result in less permanent deformation. So i consider that my material is viscoelastic material. Is that correct?. And also need how i assign the material properties of viscoelastic material for compression test in any analysis software
Hello. I have experimental test data from ASTM C473 of gypsum. How can I calibrate a material in Abaqus given only flexural test data?
