Based on a one-dimensional discrete system of bistable springs, a mechanical model is introduced to describe plasticity and damage in carbon nanotube (CNT) arrays. The energetics of the mechanical system are investigated analytically, the stress-strain law is derived, and the mechanical dissipation is computed, both for the discrete case as well as for the continuum limit. An information-passin...

This paper will focus on aspects of the advanced analysis and underlying behavior of composite structures with concrete-filled steel tube (CFT) columns. Through a detailed examination of the results of a suite of full-scale slender CFT beam-column tests, insight into the cyclic behavior of such members is gained, specifically pertaining to local buckling of the steel tube and the plastic hinge ...

A novel thermodynamically consistent cohesive-frictional model for the analysis of interface degradation and failure under either monotonic quasi-static loading or cyclic in low-cycle fatigue problems is proposed. Starting from definition a suitable Helmholtz energy density function, phenomenological developed framework plasticity damage mechanics. In particular, coupled plasticity-damage activ...
