Analysis of Five Parameter Viscoelastic Model Under Dynamic Loading
The purpose of this paper is to analysis the viscoelastic models under dynamic loading. A five-parameter model is chosen for study exhibits elastic, viscous, and retarded elastic response to shearing stress. The viscoelastic specimen is chosen which closely approximates the actual behavior of a polymer. The module of elasticity and viscosity coefficients are assumed to be space dependent i.e. f...
متن کاملTissue- and Microstructural-level Deformation of Aortic Tissue under Viscoelastic/Viscoplastic Loading
Mechanical function of tissues in health and disease is regulated through interactions of phenomena spanning across multiple length scales. The multiscale nature of tissue biomechanics should be incorporated into modeling approaches if a full description of soft tissue biomechanics is sought [1-4]. While gross changes in geometry are sufficient for quantifying tissue-level deformations, quantif...
متن کاملA first damage modelling of SiC-SiC laminates under dynamic loading
A first mesomodelling, which allows us to describe the mechanical behaviour of an elementary ply within a SiC-SiC laminate under dynamic loading, is proposed. Questions related to its identification and its use for the prédiction of the dynamic fracture of laminated structures are discussed.
متن کاملPrediction of Crack Initiation Direction for Inclined Crack Under Biaxial Loading by Finite Element Method
This paper presents a simple method based on strain energy density criterion to study the crack initiation angle by finite element method under biaxial loading condition. The crack surface relative displacement method is used to eliminate the calculation of the stress intensity factors which are normally required. The analysis is performed using higher order four node quadrilateral element. The...
متن کاملPeridynamic modeling of composite laminates under explosive loading
High velocity impact and shock or blast responses are a critical design characteristic determining sizing of composite parts and, ultimately, weight savings. This study demonstrates the applicability of peridynamics to accurately predict nonlinear transient deformation and damage behavior of composites under shock or blast types of loadings due to explosions. The peridynamic predictions correla...
