Low Velocity Impact of Sandwich Composite Plates
Impact and compression after impact properties of plain weave carbon fiber sandwich composites were investigated in this study. Impact tests were conducted on different sample types to obtain information about absorbed energy and force. The different samples consisted of foam filled and hollow honeycomb cores with four layer carbon fiber sheets on one or both sides. The impact and compression a...
متن کاملLow-velocity Impact of Sandwich Composite Plates
In this paper we investigate impact and compression after impact properties of plain weave carbon fiber sandwich composites. Impact tests were conducted on different sample types to obtain information about absorbed energy and maximum impact force. The different samples consisted of foam-filled and hollow honeycomb cores with four-layer carbon fiber facesheets on one or both sides. The impact a...
متن کاملBuckling Analysis of Spherical Composite Panels Reinforced by Carbon Nanotube
In this study, the buckling behavior of moderately thick Carbon Nano-Tube (CNT)-reinforced spherical composite panels subjected to both uniaxial and biaxial loads is examined. The uniform and various kinds of functionally graded distributions of the CNT are considered. The mechanical properties of the nanocomposite panels are estimated using the modified rule of mixture. Based on the first-orde...
متن کاملLow Velocity Impact of Flat and Doubly Curved Polycarbonate Panels
Three-dimensional finite transient deformations of polycarbonate (PC) panels impacted at low velocity by a hemispherical-nosed rigid cylinder have been studied by using the commercial finite element software LS-DYNA with a thermo–elasto–viscoplastic material model for the PC incorporated in it as a user defined subroutine. The implementation of the subroutine has been verified by comparing anal...
متن کاملAnalytical Prediction of Indentation and Low-Velocity Impact Responses of Fully Backed Composite Sandwich Plates
In this paper, static indentation and low velocity impact responses of a fully backed composite sandwich plate subjected to a rigid flat-ended cylindrical indenter/impactor are analytically investigated. The analysis is nonlinear due to nonlinear strain-displacement relation. In contrast to the existed analytical models for the indentation of composite sandwich plates, the stacking sequence of ...
