Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

A six degree of freedom passive vibration isolator with quasi-zero-stiffness-based supporting
Journal of Low Frequency Noise, Vibration and Active Control, 2018 A six degree of freedom nonlinear passive vibration isolator is proposed based on Stewart platform configuration with the quasi-zero-stiffness structure as its legs. Due to the high static stiffness and low dynamic stiffness of each leg, the proposed six

Nonlinear behavior of quasi-zero stiffness nonlinear torsional vibration isolator
Nonlinear Dynamics, 2023 Abstract This paper researches the nonlinear behavior of a nonlinear torsional vibration isolator (NTVI) which is composed of flexible rod element and electromagnetic element. And the NTVI has a quasi-zero stiffness (QZS) characteristic. Firstly, a statics model of the QZS-NTVI is established and the effects of geometric parameters on the QZS ...
