CE 515 Advanced Strength of Materials

Fundamentals of stress, strain and deformation, linear elastic theory, elastic bodies: isotropic, anistropic and orthotropic constitutive equations; St. Venant's classical theory of torsion: non-circular bars, thin-walled open sections, thin-walled single-cell tubes, multi-cell thin-walled tubes; unsymmetric bending and transverse shear, shear flow and shear center in thin-walled sections, nonlinear beam, shear deformation of beams, curved beams; stress concentration, beams on elastic foundations, introduction to plasticity theory, and introduction to fracture mechanics. 3 credit hours.


• Prerequisite

Undergraduate course on Mechanics of Solids

• Course Objectives
By the end of the course, the students will be able to:
  • Analyze stresses and strains at a point: transform stresses and strains, determine principal stresses and strains and principal directions for 3D problems, and analyze strain rosette data.
  • Use the elastic and orthotropic constitutive equations for establishing relationship between 3D stresses and strains.
  • Use approximate theories of strength of materials for engineering stress and strain analyses of open and closed thin-walled sections subjected to torsion and unsymmetric bending.
  • Analyze curved beam, beams on elastic foundation, shear deformation of beams, and stress concentration problems.
  • Perform failure analysis using classical plasticity theory and fracture mechanics.

• Course Requirements

Homework: Will be assigned weekly and due EXACTLY in one week from day of assignment. Late submission will not be accepted without a valid reason.

Exams: one test and one final
