Compression test - Essay Example he lateral forces acting on the can ultimately act on a single line, which is, takes a rectangular shape and is relatively small in area, thus the quick crumbling. Once the yield point, or yield stress, has been reached, the crumbling requires less force for continued deformation, thus the dip in the force used. When the compressive load is directed onto the tops of the soda can, the compressive force acts on the wholesome vertical wall of the can, thus distributing the force equally. By distributing the forces subjected to the can equally as opposed to a single point in the side-crushing test, the can has more resistance to the compressive forces. Since the can is hollow, it exhibits characters that are varied as opposed to the side crushing. From the graph, when the forces supplied reach the yield point, there is a drop in the required forces (Voland, 2003, p. 192), but the crumble suddenly strengthens the can as it is compressed, and gets compacted. The can requires a lot more force to continue the deformation, thus the curve that gets a positive gradient as opposed to a continued drop. The changes are not uniform since the compacting assumes various strengths with continued compacting, until the ultimate load is reached. The forces show that the can takes of fragile characteristics as o pposed to ductile traits in the compression tests, since the graph changes are sudden as opposed to the curved changes a ductile object displays. The relationship between the force and the standard travel (deformation) is proportional, though there exists a constant since the change does not begin at the origin for both
