Finite Element Simulation Models for Mechanics of Materials

In this paper the creation and utilization of a set of virtual models for complementing a Mechanics of Materials course in the Civil Engineering and Construction Management Department at Georgia Southern University is outlined and discussed. The simulated models are developed utilizing the Abaqus finite elements package. The models can particularly be useful in cases where a physical lab is not accompanying the offered course, as is the case in the authors’ institution. Several examples of the developed simulations are provided in the paper to better illustrate the utility and significance of the models. The simulations for example can be used to determine and display the stress and deformation contours at various locations on the solid continuums having different geometries, boundary conditions, material properties, and loading conditions. The models are specifically developed to be used by the course instructor in illustrating and explaining some of the more important mechanics principles and concepts. These visual simulations help students better comprehend the course concepts and more easily understand the limitations and assumptions used in the classical formulation of mechanics problems. Some of the examples explored in the project include the analysis of axially loaded members, torque loaded shafts, bending of beams, combined loading of structural members, and pressurized thin-walled vessels. As an added measure to further maximize the effect of the project and to creatively enhance the educational effect of the undertaken project for our program as a whole, the developed modules for the mechanics of materials are also planned to be utilized in a newly developed undergraduategraduate finite element course offered in spring 2017. Obviously, the intent for utilization of these models in the FE course will be different than what is previously described for the mechanics course. In the FE course, the created examples are specifically used to illustrate the actual details and procedures that need to be followed to properly model and analyze a solid continuum. Using these examples, the students will be coached to develop the solution for other similar problems. The newly developed simulations can in turn be used in future offerings of the mechanics of materials course.
