Abstract: A helical spring that is constrained to no rotation has a compliance that is typically more than 95% of the compliance of springs constrained to free rotation when restricted to symmetric ...

Abstract: Two linear elastic models for describing stresses in center-wound rolls have been compared. One model includes wound on residual strains from the web while the other uses a clamped on stress ...

Abstract: An experiment was designed to relate force to plastic deformation caused by a wedge indenting the edge surface of a polymer sample. The experiment reveals the primary phenomena observed in ...

Abstract: A finite element method by Roddeman was modified in order to study wrinkling of polymer membranes due to mechanical loads and thermal shrinkage. Thermal shrinkage was incorporated as a prestrain ...
