Show that an orthotropic material whose principal stiffnesses satisfy the following relations is isotropic: C11 = C22 C662 (C11 C12) How would you do this? Show that 1. C11, C12, and C66 are independent of orientation 2. and that C16 = C26 = 0 Show that an orthotropic material whose principal stiffnesses satisfy the following relations is isotropic: C11 = C22 C662 (C11 C12) How would you do this? Show that 1. C11, C12, and C66 are independent of orientation 2. and that C16 = C26 = 0
