纤维金属层板鸟体高速冲击损伤预测及失效分析
Damage Prediction and Failure Mechanism of Fiber Metal Laminates under High Velocity Bird Impact
摘要
Abstract
For the potential risk to aviation safety caused by bird impact,a nonlinear finite element model based on continuum damage mechanics is developed for fiber-metal laminates commonly used in aviation structures to investigate their mechanical behavior under the high velocity bird impact.The Mie-Grüneisen equation of state is introduced to describe the hydrodynamic-like behavior of bird under high velocity impact and the adopted the smooth particle hydrodynamics (SPH) method to model the bird.A unidirectional composite intra-laminar damage prediction model considering strain rate is adopted and the VUMAT subroutine is written.Johnson-Cook model and bilinear cohesive zone model are applied to identify the aluminum layer damage and the delamination of interface.Based on ABAQUS/Explicit solver module,the dynamic response of fiber metal laminate under different bird masses and impact velocity conditions is simulated.The damage characteristics of the laminates and the material failure mechanism are analyzed in detail,which provides a reference for the numerical analysis of the bird impact issues on the fiber metal laminates.关键词
