Introduction to elastic and plastic deformation; Elementary dislocation theory and twinning; Strengthening mechanisms; Fracture; Fatigue; Creep. Although this course focuses more on crystalline materials, the essential information related to mechanical behaviour of polymers will also be provided.
Lab: Tensile test of various materials (low carbon steel, copper, aluminium, HPDE polymer). Compression test (zinc, brass, copper). Macro- and micro-hardness test (effects of grain size and carbon content), creep (Sn-based, lead-free solders). Rotating bending fatigue testing (steel). Charpy impact test (high carbon steel, copper).
Theory: Fracture, fatigue and creep. Data and error analysis. Workings of an equipment (including sensors and controllers).
Quick recap of relevant mathematical concepts, equations of equilibrium and compatibility conditions (structural problem) and stress (Airy) function. Philosophy of FEM. Fundamentals of FEM, such as concepts of discretization, interpolation functions, assembly of equations and solution. Application of FEM for solving differential equations using Galerkin method and variational equations using Rayleigh - Ritz method. 1-D, 2-D and 3-D example problems in elasticity and heat transfer. Solving linear and non-linear structural, thermal and electrical problems using a commercial FEM software (mostly, ANSYS).A Short Course on crystal plasticity (including basic usage of DAMASK) by Professor Philip Eisenlohr of Michigan State University
The FEM component of the course involves both basic theory and training on ANSYS software. The syllabus for FEM includes the following:
Theory: Philosophy of FEM; Galerkin Method; Solving 1-D heat transfer and solid mechanics problem; Formulation of generic finte elements; errors and convergence.
Tutorial: Compression test of elastic-plastic material; Elastic fracture mechanics; Transient indentation of elastic-plastic material
