Integrating a Research Problem in a Course in Applied Elasticity

Abstract

An example of integrating a single research problem over a broad range of topics in a graduate-level course in applied elasticity (advanced strength of materials) is given in this paper. The research problem was obtained from an investigation of failures during the assembly of fulcrums of bascule bridges. Topics exemplified by using this problem included interference fits, axisymmetric problems, transformation of strains and stresses, comparison of failure theories, and the effect of temperature-dependent thermoelastic properties.

On introducing approximate solution methods in theory of elasticity

“…In 2000, this effort was followed by integrating a single research problem [3,4] of assembling fulcrums of bascule bridges into the classroom [5]. This research problem had broad-based use in exemplifying multiple concepts such as interference fits, axisymmetric response problems, transformation of strains and stresses, comparison of failure theories, critical crack length aspects, and effect of temperature dependent thermoelastic properties.…”

Incorporating A Research Problem In A Numerical Methods Course For Mechanical Engineers

“…The data given in Table 1 is minimum or does not change appreciably is the optimum order of the polynomial. 4. Regression models obtained using default Excel® format do not properly account for significant digits, and hence create artificial large differences between the observed and the predicted values.…”

“…Incorporating a research problem into a graduate level course 4 presents challenges, and to incorporate a problem into an undergraduate level is even more challenging. These challenges include 1. the research problem may not address most of the topics of the course to justify the use of class time, 2. specific skills may be needed that are too time consuming to teach, 3. the problem may be out of scope for the education level of the students.…”
