HI everyonei didn't change model a lot as in this situation safety is very importantvon Mises stress field of my design under P1 P2 P3 load case
weight=89kgsimscaledeformation= 1.87e-3Allowed maximum von Mises stress 3.05e+8 <3.5 e+8
solidworksweight=89kgi have given AISI1020 coll rolled as materialmax deformation = 1.916 mmAllowed maximum von Mises stress = 350 smaller than 355
