As estimates of the transverse shear stresses are available at section integration points as output variables TSHR13 or TSHR23. For Simpson’s rule output of variables TSHR13 or TSHR23 should be requested at nondefault section points, since the default output is at section point 1 of the shell section where the transverse shear stresses vanish.

then how to trace this transverse shear stress at nondefault section points....

Please check the following link for analysis test problem by ABAQUS SIMULA, and suggest :

how to trace this Figure 1.1.3-8, 9 , 10 etc, as this model consists of 2 and 3 element in thickness direction but graph is plotted with more number of output points..... I can understand that, these grapes are plotted by tracing stresses at thickness integration points, but how to trace these transverse shear stresses at these thickness integration points. please help......
