ES125: Mechanical Systems
Fall 2011, Fall 2012, Fall 2013
Modeling and analysis of mechanical and some electromechanical systems. Topics include resonance, damping, frequency response, Laplace Transform methods, Lagrange's equations, multiple degree-of-freedom systems, and 3-D rigid body dynamics. Computer exercises on simulation of linear and nonlinear dynamic systems. Laboratory: experiments on vibration, stabilization, and complex dynamical systems using modern electronic instrumentation and data reduction systems. Computer simulations of a few systems will become laboratory exercises. By the end of this course you will be able to analyze complex mechanical systems. This course will give you the physics and mathematical foundation necessary to describe the dynamics of many of the devices and structures that we encounter daily.
ES128: Introduction to Computational Mechanics
Spring 2010, Spring 2012, Spring 2014
Introduction to computational techniques for the simulation of a large variety of engineered systems. The application to real engineering applications are stressed throughout. Introduction to finite element methods for analysis of steady-state and transient problems in solid, structural, fluid mechanics, and heat transfer. Modeling of problems and interpretation of numerical results. Implementation of simple MATLAB codes and use of existing general-purpose programs (ABAQUS). Final project addressing a significant problem arising in engineered systems.
ES242r: Finite elements for analysis and design
Spring 2011, Spring 2013
The key goal of this class is the application of the finite element method to classical and state-of-the-art modeling and design problems. We introduce a commercial finite element program - ABAQUS - and demonstrate how to use it in modeling and analyzing design problems. Topics include the implementations of user-defined subroutines (UMAT and VUMAT), instability analyses, analysis of waves propagation, fluid-structure interactions. To take this course, basic knowledge and general interest in finite elements, mathematics, strength of materials, structural and solid mechanics is highly recommended.
