Abstract: Atherosclerosis occurs when plaque clogs the arteries. It is a leading cause of death in the United States and worldwide. In this paper, we study the bifurcation for a highly nonlinear and highly coupled PDE… read more here.

Abstract: Abstract The thermoelastic response of aerospace structures is significantly influenced by structural nonlinearities and conventional design tools based on assumption of linearity prove to be insufficient. A nonlinear analysis of the thermoelastic response of aerospace… read more here.

Abstract: We theoretically investigate the nonlinear behavior of a buckled tip near the bifurcation point under external stress. We present a mechanical model for the buckled tip and derive the governing equation that describes the "buckling-to-flipping"… read more here.
