Hi:

I am using the nine node quadrilateral element to model a 30m deep soil column with 10 different material layers under earthquake excitations. However, the dimension of the stress output file is different from that of the strain output file. Therefore, I have trouble finding out which stress output is corresponding to which strain output. Can anyone please tell me how many stresses does the 'stress' recorder actually recordes per element? Or how to plot the shear stress vs strain curve in general?

regards
