ENGR 3311: Mechanics of Materials

Description

     This course deals with material that is the background for engineering design. Engineered products are subject to various kinds of stress in service such as normal stress, shear stress, and bending stress. Under the influence of the stresses the engineered product could break (or rupture) of deflect excessively. Under some circumstances the engineered product may buckle down and fail. It is important that the engineer design machine members and structures that do not fail in any conceivable way. In order to do this, the engineer needs to evaluate the stresses that may be present in engineered products due to various loads (forces and moments). Once this stress is evaluated, suitable material and/or dimensions could be chosen so as to render the product failure proof. Essential background information for this course is drawn from Materials Science and Engineering Mechanics.  
 

Course Objectives

  • Understand the concepts of linear elasticity, including Hooke's Law and Poisson's Ratio.
  • Be able to define normal and shear stresses and calculate their values for members with known external axial and lateral forces, torques, and bending moments.
  • Be able to define normal and shear strains and to calculate their values for members with known stresses.
  • Understand the basic geometries of beams and be able to perform analysis of internal stresses, including the determination of maximum values for shapes common to engineered structures.
