Low Velocity Impact Damage Prediction in Laminated Composite Plates
In this paper, a finite element model is presented for the transient analysis of low velocity impact, and the impact induced damage in the composite plate subjected to low velocity impact is studied. The failure criteria suggested by Choi and Chang and the Tsai-Hill failure criteria are used for the prediction of the damage in the composite plate; then the effect of various parameters on the im...
متن کاملSensitivity analysis of low-velocity impact response of laminated plates
We analyze the sensitivity to values of material parameters, layer thickness and impact speed of the plate deflection, the contact force between the impactor and the plate, the maximum length of a crack, and the energy dissipated during the low velocity impact at normal incidence of a clamped rectangular laminate by a rigid hemispherical-nosed cylinder. The laminate is comprised of layers of po...
متن کاملThe Dynamic and Vibration Response of Composite Cylindrical Shell Under Thermal Shock and Mild Heat Field
In this article, the vibration and dynamic response of an orthotropic composite cylindrical shell under thermal shock loading and thermal field have been investigated. The problem is that the shell is initially located at a first temperature, and some tension caused by a mild heat field is created, then the surface temperature of the cylinder suddenly increases. The partial derivative equations...
متن کاملModeling Impact Damage in Laminated Composite Plates
The simulation of impact damage in laminated composite plates presents many challengesto modelers. Local failure takes the form of various fracture processes. For compositesthis is further complicated because the various modes can strongly interact with each other.Another modeling challenge particular to composite materials is that it is often necessaryto simulate the struct...
متن کاملParameter sensitivity of anisotropic elasto-plastic shell
1.Abstract A continuum-based design sensitivity analysis (DSA) applied to the thickness design of the anisotropic elasto-plastic shell structures is developed. Since main interest lies in developing path-following algorithms for solving sensitivity problems of elasto-plasticity, such an incremental or a step-by-step formalism will be employed to implementation into the structural analysis progr...
