Thermal coupling analysis of lightning strike laminates
Journal of Aeronautical Materials, 2020 In order to study the ablation damage mechanical properties of composite laminated plate under the action of lightning current, a thermal-mechanical coupling finite element analysis model of composite lightning strike was established. The validity of the

Microstructure Based Failure Criterion For Ductile Materials
EPJ Web of Conferences, 2018 For ductile metals, the process of dynamic fracture occurs through nucleation, growth and coalescence of voids. The stress required to nucleate these voids is inferred from the velocimetry data (using the acoustic approach) and termed as the spall ...

Failure criteria for C/SiC composites under plane stress state
Theoretical and Applied Mechanics Letters, 2014 The applicability and limitation of several quadratic strength theories were investigated with respect to 2D-C/SiC and 2.5D-C/SiC composites. A kind of damage-based failure criterion, referred to as D-criterion, is proposed for nonlinear ceramic ...

Failure criterion for metallic glasses [PDF]
Philosophical Magazine, 2011 Metallic glasses exhibit not only multiple failure modes but also differences in ultimate strength, plastic strain to fracture and asymmetric deviation of failure angles from 45 degrees between tension and compression. The available failure theories cannot fully characterize these phenomena and the underlying physics has not been completely clarified ...

A Macroscopic Strength Criterion for Isotropic Metals Based on the Concept of Fracture Plane
Metals, 2019 Although the linear Mohr−Coulomb criterion is frequently applied to predict the failure of brittle materials such as cast iron, it can be used for ductile metals too.

Optimization of laminates subjected to failure criterion [PDF]
Metalurgija, 2011 The paper is aimed on laminate optimization subjected to maximum strain criterion. The optimization problem is based on the use of continuous design variables. The thicknesses of layers with the known orientation are used as design variables.
