Is the CST element more accurate than bilinear element (Q4) for bending problems?

Submitted by QINGCHENG YANG on Tue, 03/04/2014 - 22:21

I did a 2D beam bending problem with CST and Q4 element, respectively. CST gives better accuracy. Is it due to the shear locking effect with Q4?

Difference between shell 99 and shell 181

Submitted by ambesange on Tue, 03/04/2014 - 14:41

Hi Friends,

I am currently writing my thesis in riser of marine and i want to model a Thermoplastic composite pipe with e glass fibers. In the pervious version of ansys they have used the shell elements 99 but in ansys 14.5 the shell element does not exist , i want to that shell element shell 181 have the similar properties of shell 99? or which other element type can be used for composite pipe ?

Thanks in advance.

Regards,

Amit
