ABSTRACT

Virtual laboratory experiments can be a useful self-learning and teaching tool for Strength of Materials. Three modules (Material Module, Bending Module, and Torsion Module) were developed and integrated with the engineering core course (ENGR 2153) offered during the Spring semester each year by the College of Engineering at the University of Oklahoma. An overview of these modules is presented in this paper. An informal evaluation of the impact of these modules was conducted. The results of this evaluation are briefly discussed.

INTRODUCTION

Strength of Materials (ENGR 2153), a sophomore-level engineering core course at the University of Oklahoma (OU), is taught Spring semester each year as one section with typical enrollment of 60 to 80 students. Although taught exclusively by the School of Civil Engineering and Environmental Science (CEES), students from Civil, Environmental, Pre-Architecture, Petroleum and Industrial Engineering take this course. One of the primary objectives of the course is to introduce the concept of stresses, strains and displacements in structures and their components due to different types of loads. The perception is that if one can determine these quantities for all types of loads, including the loads that cause failure, one will have a complete picture of the mechanical behavior of these structures (Gere and Timoshenko, 1997). An understanding of mechanical behavior is essential for the safe design of all types of structures, whether airplanes and antennas, buildings and bridges, machines and motors, or ships and spacecrafts. The contents of the Strength of Materials course at OU can be divided into the following three broad categories: (1) Material Behavior: Stress, stress transformations, strain, strain transformations, stress-strain relationships, and laboratory procedures to obtain mechanical properties of materials. (2) Member Behavior: Stresses and deformations in various types of members including axial, torsional, bending, transverse shear, and members under combined
