摘要：

This article deals with the response of GLARE (GLAss REinforced) fiber-metal laminates subjected to frictional oblique indentation. The indentation response is initially predicted using ANSYS software and a three-dimensional analysis with geometric and material nonlinearities. The classical Coulomb friction model is employed to simulate friction between the contacting surfaces. Then, analytical formulae are derived to predict the GLARE plate indentation load and strain energy as a function of the indentor's displacement, the friction coefficient, and the indentation direction. These formulae are applied successfully for the GLARE plates with various diameters and indentation directions. The analytical results agree very well with the corresponding finite element analysis results.
