1. What is the difference between isotropic and anisotropic materials ? Ans: If a material exhibits same mechanical properties regardless of loading direction, it is isotropic, e.g., homogeneous cast materials. Materials lacking this property are anisotropic.   2. What are orthotropic materials ? Ans: It is a special class of anisotropic materials which can be described by giving their properties in three perpendicular directions e.g. wood; composites.
