HI everyone i didn't change model a lot as in this situation safety is very important von Mises stress field of my design under P1 P2 P3 load case
weight=89kg simscale deformation= 1.87e-3 Allowed maximum von Mises stress 3.05e+8 <3.5 e+8
solidworks weight=89kg i have given AISI1020 coll rolled as material max deformation = 1.916 mm Allowed maximum von Mises stress = 350 smaller than 355
