JNTUK B.Tech Plasticity and Plastic deformation gives you detail information of Plasticity and Plastic deformation R13 syllabus It will be help full to understand you complete curriculum of the year.
(Course Objective: To integrate knowledge of maths, science and manufacturing Engineering already acquired to understand deformation mechanism and various deformation theories of plasticity which may ultimately lead to understanding of material behavior that may help to produce quality products).
UNIT – I : (Learning objective: To understand the concept of plastic deformation, the phenomenon of cold working and workability under varied service conditions) The interaction of material properties and process variables in plastic deformation processes. Phenomena of hot, warm and cold working. Flow stress and workability. Effect of hydrostatic pressure.
UNIT–II: (Learning objective: To understand the 3D stress analysis and plastic instability along with component behavior under real working conditions) 3D stress analysis, plastic deformation and terminology, yield criteria and stress – strain relationships, work-hardening, plastic instability.
UNIT–III: (Learning objective: To understand and acquire knowledge of the elastic theory of materials under real conditions)
Elasticity Theory: The State of stress and strain, Two dimensional stress analysis, Plane stress, Plane strain, Equations of compatibility, Stress function, Boundary conditions, stress and strain tensor, tensor transformation, anisotropy , elastic stress-strain relation and elastic behaviour of anisotropic materials.
UNIT–IV: (Learning objective: To understand the importance of various yield criteria and other aspects about yielding during deformation in real conditions) Yielding and Plastic Deformation: Hydrostatic and Deviatoric stress, Octahedral stress, yield criteria (Von Mises and Tresca), texture and distortion of yield surface.
UNIT–V: (Learning objective: To understand the plastic deformation problems using slip line field theory to develop deformation models) Slip line field theory: convention for slip lines, solutions of plastic deformation problem, Geometry of slip line field, Properties of the slip lines.
UNIT–VI: (Learning objective: To solve the plastic deformation problems using slab method, upper bound and lower bound methods under varied service conditions) Formulations of plastic deformation problems, application of theory of plasticity for solving metal forming problems using Slab method, upper and lower Bound methods, Slip line field theory.
(Course outcomes: The student should be able to
- understand dislocations and mechanical behavior of materials under elastic and plastic deformation at different strain rates.
- Estimate the strength of the material for cold, warm and hot working conditions.
- Use the data gathered to carryout design of various systems under given service conditions properly)
(Assessment: The student should be evaluated based on the assignments aand objective tests. The student’s analytical abilities (with special focus on academically weak students) should be tested periodically in classes by giving problems). Emphasis should be given by conducting tutorial classes at the end of each unit.)
