hi!  I want to model tsai wu failure composite in Abaqus.  this is my lamina properties,133860    7706    0.301    4306    4306    2.76 and failure stresses are 1830    -1096    57    -228    71    -1    0, i am creating a rectangle of 1000 by 1000 with 0 90 -45 45 and 1.25 thickness. I am applying 70.7107 load in x and y direction as shell edge load. the BC is only u1/u2/u3 displacement rotation blocked in the Centre.   I am not getting the same factor as classsical laminate theory.  I am getting 1.604e-5 minimum factor which will result 250  but in CLT i am getting 172.
