Applications of finite element modelling in failure analysis of laminated glass composites: A review

摘要

The subject of the paper is modelling of complex damage behaviour of laminated glass, which is a sandwiched polymer composite. Last 20 years have witnessed extensive growth in computational modelling of complex nonlinear behaviour of laminated glass panels with viscoelastic interlayers. Present review article is an attempt to highlight applications of finite element approach in failure analysis of laminated glasses. Evolution of modelling theories such as equivalent single layer theories, layerwise theories and zig-zag models have been presented to insight the fundamental concepts used in modelling. Finite element techniques such as erosion, cohesive zone and extended finite element methods available in FE packages are briefly reviewed alongwith material models for glass and interlayer. The systematic growth in FE models in numerical simulation of human head impact on windshields and blast loading is specifically presented. Finite element models have been proposed as useful guides to engineers for fabrication of laminated glasses with more realistic data to be used in real world situations without going for expensive and time consuming experimental set ups. Overall 223 research articles have been included exhibiting the research performed in context of laminated glass.
