warpage of second order tria and quad element

pratik gadve

I have been asked in an interview- ' Does only quad element warp ? '

I said 'yes'.

'Then what about second order tria elements ? do they warp ? '

I was confused because there is possibilty of warpage due shifting of middle node in second order elements. I guess It will get warp.

Will you please tell correct answer  for above questions with correct explaination.

Thanks and Regards,

Pratik
