A considerable number of protective structures have been constructed in the appearance of a glass house and transparent materials such as glass, plexi glass and polycarbonate sheets are used in façade and roof construction. The main reason for using transparent materials is.

Isotropic elastic materials are the special cases for which the Cauchy stress tensor σ depends solely on the left Cauchy-Green strain tensor B=FF.
