Engineering constant transformation
Engineering constant transformation
(OP)
Hi, i am doing the fem analysis of orthotropic pressure vessel in Ansys. It require to enter the 9 transform engineering constant for unidirectional composite . In most of composite book, they provide the transformtion of FT in XY plane. but what about the transformation normal to XY plane. i mean transforamtion of Et' to Ez, similarly transformation of Vft',Vlt',Gft',Glt', if i rotate the fiber through some angle in XY plane.
Is there any reference, which can provide me the transformation equation of these 9 engineering constant.
