ED4201 Mechanical Behavior of Materials Syllabus:

ED4201 Mechanical Behavior of Materials Syllabus – Anna University PG Syllabus Regulation 2021

COURSE OBJECTIVES:

The main learning objective of this course is to prepare the students for:
1. Analyzing the different strengthening and failure mechanism of the metals
2. Applying the effects of metallurgical parameters in the materials design
3. Analyzing the relationship between the selection of materials and processing
4. Developing the novel material through understanding the properties of the existing metallic materials
5. Analyzing the different materials used in the engineering applications

UNIT-I BASIC CONCEPTS OF MATERIAL BEHAVIOR

Engineering Design process and the role of materials; materials classification and their properties, Strengthening mechanisms-grain size reduction, solid solution strengthening, strain hardening, grain boundary strengthening, precipitation, particle, fibre and dispersion strengthening, Effect of temperature, strain and strain rate on plastic behavior–Super plasticity–Failure of metals

UNIT-II BEHAVIOUR UNDER CYCLIC LOADS AND DESIGN APPROACHES

Stress intensity factor and fracture toughness–Fatigue low and high cycle fatigue test, fracture mechanisms and Paris law.-Effect of surface and metallurgical parameters on fatigue– Safe life, Stress-life, strain-life and fail-safe design approaches-Fracture of non metallic Materials–Failure analysis, sources of failure, procedure of failure analysis

UNIT-III SELECTION OF MATERIALS

Selection of materials based on function, Objective, Constraints, free variables and service requirements – Relationship between materials selection and processing – Case studies in advanced materials selection with relevance to aero, auto, marine, machinery and nuclear applications

UNIT-IV MODERN METALLIC MATERIALS

Steels-Advanced high strength steel, Dual phase (DP) steel, Transformation induced plasticity(TRIP) Steel, Maraging steel, Nitrogen steel, Austenitic steel and Q&P steels – Intermetallics, Niand Tialuminides – Alloys – Al, Mg, Cu, Superalloys- Ironbase, Cobaltbase, Nickelbase. Metalmatrix composites (MMC).

UNIT-V NONMETALLIC MATERIALS

Polymeric materials–Formation of polymer structure, properties and applications of engineering polymers, Environmental aspects of polymers – Ceramic- Advanced ceramics, WC, TIC, TaC, Al2O3, SiC, Si3N4CBN and diamond– Fracture of ceramics-Stress strain behavior Deformation behavior. Glasses- Clay products-refractory ceramics, Composite Materials-GFRP and CFRP laminated composite.
