Mechanical response of polyether polyurethane foams under multiaxial stress and the initial yielding of ultrathin films Dai, Xiangyu (2010-05-19)In the first part of this thesis, we study the mechanical response of elastic polyether polyurethane (EPP) foams by means of experiments, theory, and modeling. The experiments include five loading cases: uniaxial compression ...
Gioia, Gustavo; Dai, Xiangyu (Department of Theoretical and Applied Mechanics (UIUC), 2005-08)Very recent experiments indicate that in free-standing metallic films of constant grain size the initial yield stress increases as the film becomes thinner, it peaks for a thickness on the order of 100 nm, and then starts ...
