Abstract
In this paper, the experimental and numerical failure analysis of Fiber Metal Laminates (FML) with dif-ferent types of cutouts, were investigated. Fiber metal laminates are types of materials which are consist of com-bination of metal sheets, especially aluminum ones, with fiber reinforced epoxy layers. At first, specimens were manufactured and elliptical and circular cutouts were cre-ated in them. Then subjected to in-plane tensional loading to carry out the behaviors, also, finite element analysis was carried out with ABAQUS commercial software. RIKS method was used in this analysis. Finally, experimental and finite element results were compared with results of elastic compensation method. DOI: http://dx.doi.org/10.5755/j01.mech.20.1.3530
Highlights
At the end of decade 1970s, the idea of using two materials for conquest of defects of both materials was suggested [1]
Soltani et al [9] studied finite element nonlinear tensional behavior of in-plane loaded GLARE plates and compared with experimental results which had been presented by Wu G. and Yang [10]
The present paper describes the results of experimental and numerical investigation into the failure and large deflection of FML plates with different types of cutout
Summary
At the end of decade 1970s, the idea of using two materials for conquest of defects of both materials was suggested [1]. P. Soltani et al [9] studied finite element nonlinear tensional behavior of in-plane loaded GLARE plates and compared with experimental results which had been presented by Wu G. and Yang [10]. Soltani et al [9] studied finite element nonlinear tensional behavior of in-plane loaded GLARE plates and compared with experimental results which had been presented by Wu G. and Yang [10] In both papers, the behaviors of in-plane loaded sheets of FML have been presented. In this analysis effect of delamination between layers, plastic behavior of Aluminum layers and damage in fibers cured by resin in FML plates with cutouts while subjecting to shear and tensional loading was investigated. Results of experimental and finite element methods are compared with the results of elastic compensation method
