Lab 8 – Combined Loading Mechanics of Deformable Solids Laboratory Spring 2011 Introduction Up to this point the laboratory has explored bending, tensile and torsion loading cases. By combining the knowledge from each case, it becomes possible to analyze cases where a combination of loads is applied simultaneously. Combined loading exists all around us in structures, mechanical components, composite materials, and within the human body. The human spine for example is routinely subjected to repetitive torque and axial compressive forces. The loading is neither pure torsion nor pure compression since they happen simultaneously and with varying magnitudes. Given the magnitudes can change, it is necessary to independently analyze each type of loading to determine the deformable behavior and failure modes for the object. Principle of Superposition In today’s experiment, a hollow steel tube and lever arm will be subjected to a case of combined loading of bending and torsion. Figure 1 displays the experimental setup without the applied load. The load can be placed either at the hook protruding from the hollow tube or at the hole in the end of the lever arm. If for example the load is placed at the end of the lever arm, the hollow rod will both bend and twist. Figure 1. Experimental setup
