Voiding mechanisms in semi-crystalline Polyamide 6 during creep tests assessed by damage based constitutive relationships and finite elements calculations

Highlights - A multimechanism model coupled with damage formulation is used to simulate creep tests. - Optimization procedure is based on both macroscopic and microscopic creep behaviour. - Experimental and numerical distributions of void volume fraction are in good agreement. - Cauchy stress tensor components are the driving parameters of void growth.

Integration of Plug-in Electric Vehicles Into Microgrids as Energy and Reactive Power Providers in Market Environment

This paper presents a coupled energy and reactive power market in the presence of PEVs. The objective function is threefold, namely offers cost (for energy market), total payment function (for reactive power market), and lost opportunity cost, all to be minimized. The effectiveness of the proposed coupled energy and reactive power market is studied based on a 134-node microgrid with and without PEV participation.
