MEC 4060 - Finite Element Analysis

2 lecture hours 2 lab hours 3 credits
Course Description
This course serves as an introduction to finite element analysis (FEA) for structural and steady-state thermal problems. In the lecture portion of the course, finite element equations are developed for several element types from equilibrium and energy approaches and used to solve simple problems. In the laboratory portion, students use a commercial, general-purpose finite element computer program to solve more complex problems and learn several guidelines for use of FEA in practice. A project introduces the use of FEA in the iterative design process. (prereq: MEC 3060 ) (quarter system prereq: ME 363)
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
  • Perform a linear stress analysis of a 3D part using a general-purpose commercial finite element analysis (FEA) program
  • Define the appropriate part geometry, material properties, element type, loading, and boundary conditions necessary as inputs to a finite element analysis
  • Interpret the output of a finite element analysis relative to the objectives of the analysis, specifically in the area of convergence and accuracy of the solution relative to the problem being analyzed
  • Interface 3D solid modeling with FEA
