Introduction to the Finite Element Method

3

Basic equations of the theory of elasticity. Energy principles. Formulation and assembly of stiffness matrices and load vectors for elastic solids. Modeling considerations. Solution methods Computer implementation of finite element and stress analysis procedures. Interpretation of computer solutions. Design applications.

This course is designed to give the student a basic working knowledge of the finite-element method (and its limitations) as applied to the static analysis of certain elastic bodies: rods, membranes, planar solids of revolution and plates. The procedures are essentially those programmed for digital computer solution of large and complex stress analysis problems. The goal is NOT to learn how to use a specific Finite Element program.

Upon course completion, students will be able to:1: Derive the stiffness matrix for an element.2: Assemble stiffness matrices to obtain the general stiffness matrix of an assemblage.3: Use appropriate displacement functions.4: Use transformation matrices to derive stiffness matrices of elements arbitrarily oriented in space.5: Use the potential energy approach to derive a stiffness matrix.6: Use Galerkin's method to derive a stiffness matrix.7: Identify the limitations of different elements, how to use them, and how to interpret results.8: Apply symmetries to simplify problems.9: Demonstrate how to treat distributed forces.10: Use the isoparametric formulation to solve complex problems.11: Solve thermal stress problems.

Located on the Daytona Beach Campus, the Jack R. Hunt Library is the primary library for all students of the Worldwide Campus. The Chief Academic Officer strongly recommends that every faculty member, where appropriate, require all students in his or her classes to access the Hunt Library or a comparable college-level local library for research. The results of this research can be used for class projects such as research papers, group discussion, or individual presentations. Students should feel comfortable with using the resources of the library.
