MAE 261B (MAE 259B)- Finite element analysis for solids and structures (2018 Spring)
Lecture, four hours; outside study, eight hours. Application of finite element method to classical and state-of-the-art modeling and design problems for solids and structures. We introduce a commercial mainstream finite element program, ABAQUS, and demonstrate how to use it in an advanced way. Topics include review of finite element method, static and dynamic linear elasticity, finite deformation of hyperelastic materials, instability analysis, fracture, and implementation of user-defined subroutines in ABAQUS. Term projects using computers. Letter grading.
MAE 156A - Advanced Strength of Materials (2017 Fall, 2018 Fall, 2020 Spring, 2020 Fall)
Lecture, four hours; discussion, two hours; outside study, six hours. Requisites: courses 82, 101. Not open to students with credit for course 166A. Concepts of stress, strain, and material behavior. Stresses in loaded beams with symmetric and asymmetric cross sections. Torsion of cylinders and thin-walled structures, shear flow. Stresses in pressure vessels, press-fit and shrink-fit problems, rotating shafts. Curved beams. Contact stresses. Strength and failure, plastic deformation, fatigue, elastic instability. Letter grading.
MAE 101 - Statics and Strength of Materials (2017 Winter, 2018 Winter, 2019 Winter)
Lecture, four hours; discussion, two hours; outside study, six hours. Review of vector representation of forces, resultant force and moment, equilibrium of concurrent and nonconcurrent forces. Area moments and products of inertia. Support reactions, free-body diagrams. Forces in simple models of mechanical and aerospace structures. Internal forces in beams, shear and moment diagrams. Stress and strain components in solids, equilibrium equations, Hooke’s law for isotropic solids. Bending and shear stresses in beams. Deflection of symmetric beams and indeterminate problems. Stresses in thin-walled pressure vessels and in circular cylinders under torsion. Letter grading.
