Unformatted text preview: Sabanci University, Faculty of Engineering and Natural Sciences, MAT 307 Composite Materials, Assignment 1&2, November 16, 2011 Instructor: Mehmet Yildiz Assignment 1: Question-1) Consider a bar of cross-section A and length L in fig.1 . A uniform tensile load P is applied to the two ends of the rod; Fnd the state of stress ( x , y , z , yz , zx , xy ) and strain ( x , y , z , yz , zx , xy ) , and strain energy per unit volume of the body. Energy is deFned as the capacity to do work. In solid, deformable, elastic bodies under loads, the work done by external loads is stored as recoverable strain energy. Assume that the rod is made of a homogeneous isotropic material of Youngs modulus, E. ig.1: Cylindrical rod under uniform uniaxial load, P. Question-2) Consider semi-circular water channels made of composite materials. They are to be used as water slide in water parks so its diameter should allow an adult to fit in safely. It is necessary to have a smooth interior slide in water parks so its diameter should allow an adult to fit in safely....
