<p>The APDL test case input at the bottom of this post illustrates a way, by selecting discreet REINF264 element table stress results (rather than nodes), to identify fibers whose SX stresses have exceeded some allowable stress. SX is always the axial component of REINF264 stress (regardless of the orientation of the REINF264 relative to the global X axis).<\/p><p>Copy the APDL below into a text file and read that text file into an interactive MAPDL session with the \/INPUT command.<\/p><p>An alternative to using EKILL might be to define a material damage law for your REINF264:<\/p><p><\/p><div> <\/div><div> <\/div><div>I can see from the table below that material damage laws are supported by REFINF264:<\/div><div> <\/div><div><\/div><div> <\/div><div>Yet another (probably easier) option might be to define bilinear isotropic or kinematic hardening laws for your REINF264 (I see these options in the table above too).<\/div><div> <\/div><div>fini<\/div><div>\/cle<\/div><div> <\/div><div>\/vie,1,1,1,1<\/div><div>\/vup,1,z<\/div><div>\/esha,1<\/div><div>\/pnu,type,1<\/div><div>\/num,1<\/div><div> <\/div><div>\/sys,del file*.png<\/div><div> <\/div><div>\/title,FIBER REINFORCED CANTILEVER BEAM<\/div><div> <\/div><div> <\/div><div>C*******************************************<\/div><div>C*** PARAMETERS<\/div><div>C*******************************************<\/div><div>l=0.100 !
