Abstract

A computer based module for stress analysis has been developed to enhance student learning in the field of mechanical design and analysis. The tool is comprised of programmed templates containing an open-ended structure for the stress analysis of structural and mechanical components. Using the templates, students are able to formulate their problems and develop their own equation sequences. To reduce the need for programming and increase the flexibility of the learning tool, commercial symbolic- manipulation software (e.g. Mathcad) is utilized for the calculations performed in the module. The module is available either as an application module or on the web for the students of specific courses in the subject area. The tool allows for faster solution of a problem, experimentation with the effect of various parameters of a problem on its solution, and graphical visualization. It is expected to generate greater student interest in the subject, resulting in better understanding of the underlying theories and principles. Additionally, it will enhance computer skills for solving technical problems, as sought by the industry and required by program accrediting agencies.

1. Introduction

Stress analysis is an integral part of the undergraduate mechanical design courses in both engineering and engineering technology programs. In the design analysis area of engineering programs students are taught the fundamental concepts related to stresses in mechanical components and their innovative applications. Students utilize their learning to formulate problems and analyze stresses for creative design purposes. On the other hand in technology programs, the focus is on utilizing efficient techniques for analysis of an existing designs to address a specific problem, and modify or improve the design. Therefore, the emphasis is mainly on mastering the routine techniques rather than creative solution of a problem. But, without the theoretical foundation, such techniques alone cannot ensure successful completion of a task.
