Tutorial Questions Q2: What are the main differences between ductile and brittle failure, give typical examples for each case. Guidelines: Your answer could cover the following aspects: - Differences in the shape of the stress strain curves, properties, etc. - Different materials behaviours/deformation - Application: Typical cases where the materials will undergo brittle or ductile failure. For example, cutting a glass with a diamond cutter is typical brittle failure process, glass drops onto the floor, failure of ceramic cutting tools, etc. Ductile failure: steel bar under tension, deformation of the car body, etc. 23: Critically discuss the material or design factors which may influence the fracture nodes of a material. Guidelines: This is an open end question, which you can draw some key points based on your understanding about fracture. For example. - Materials properties (yield stress, fracture stress, etc.). - Materials microstructure, for example inclusions. \( \bullet \) Design: corners, shoulders, etc.
