    FEA - failure location in tensile test

    Hello Prost, I understand the physical test very well and agree with you 100% on your explanation. But my question is about the FE simulation. How the failure/necking location is predicted in tensile test(FEA)?... Thx, Puli888

    FEA - failure location in tensile test

    Hello coros/prost, Thanks,but my question is not about simulating the necking behaviour,rather about deciding the location of necking/failure. Since the cross section of gauge length is uniform,all element with in the gauge must get same stress & strain.Then how come suddenly few elements...

    FEA - failure location in tensile test

    Hello FE Gurus,Please help me to understand the failure mechanism in FE. Lets consider the simple 1-D tensile test. During actual test,the sample starts necking arround the location where the material is weak within the gauge length( may be porosity or some other material functions). How this...

    Influence of tensile gauge length on FS

    Hi, Lets say I have a FE model with approximate element size 15mm.It is non-linear dynamic model use LSDYNA.I do not have material stress-strain relation.So,I experimentally measured eng stress-stress data using 1D tensile test with gauge tensile length of 10mm,25.4mm and 50 mm with...
