| Aim: This course is intended to deepen the students knowledge in the theory of plasticity and its applications, and to give an introduction to fracture mechanics. The capability of materials to sustain plastic deformation can be made use of in many areas. Materials can be used more effectively by allowing plastic deformation. In production techniques, plastic processing of materials often occur, which involves large plastic deformation. Modern methods to determine whether fracture will occur with different loading conditions will be presented. Different methods will be discussed for dimensioning against crack growth and fracture with applications to some important engineering structures. Applications of the Finite Element Method in plasticity will also be discussed.Prerequisites: For Y4: Theory of elasticity, continuum mechanics, the Finite Element Method and Structural Optimization. For M4: Solid Mechanics I and II, Continuum Mechanics, the Finite Element Method, and Structural Optimization.Course organization: This course is divided into two parts:Course content: Theory of plasticity: Review of basic principles, constitutive relations, yield criteria and flow laws, deformation hardening, Bauschinger effect, applications to simple structure and material processing problems, finite element techniques for plasticity. Fracture mechanics: fracture modes, ductile and brittle fracture, linear fracture mechanics, stress fields around cracks, fracture toughness, criteria for instable crack-growth, conditions for stable crack-growth, non-linear fracture mechanics, fatigue.Course literature: Hinton, E.: Introduction to Nonlinear Finite Element Analysis, NAFEMS, Glasgow, 1992.
