With the increasing requirements of automotive lightweighting, metal/CFRP laminates are increasingly used. In this paper, Al/CFRP were prepared using an integrated hot press curing method, and optimum conditions determined single-lap shear test at 130 °C for 45 min. The effects fiber lay-up, forming speed, metal layer thickness on bending springback investigated V-shaped Abaqus finite element a...

A modified strain-rate dependent (SRD) spring-mass model was first developed to capture the strain rate effect on response prediction of fiber-reinforced polymer (FRP) laminates subjected low-velocity impact (LVI). The constitutive relations FRP material were with impact-induced using Yen-Caiazzo’s function in space and time dimensions simultaneously. stiffness coefficients updated step-by-step...

This paper is devoted to the numerical and experimental study of ductile fracture in bulk metal forming 2017A-T4 aluminum alloy. From an standpoint, alloy investigated under compressive load. Two cross-sections solid hollow specimens are considered. The mechanical behavior microstructure were characterized. It found that well-known barrel shape obtained when a load applied. Analyses topographie...

Abstract In this paper, a general three-dimensional finite element model composed of eight-node three-dimension cohesive elements and solid with reduced integration for low-velocity impact analysis composite materials is established. Firstly, the continuum damage mechanics applied to simulate initiation evolution intra-laminar damage. Based on zone , are inserted between layers predict inter-la...

Abstract Out-of-plane mechanical properties of the riveted joints restrict performance wing box assembly airplane. It is necessary to investigate pull-through composite/metal in order guide riveting design and ensure safety assembly. The progressive failure mechanism composite/aluminum joint subjected loading was investigated by experiments finite element method. A damage model based on Hashin-...

Up to now a large number of models have been developed to measure or predict the damage in equipments. Some of these models have been implemented in ABAQUS software. To implement damage parameters in the software, it is necessary to perform complex and expensive practical tests. One of these damage models is Forming Limit Diagram (FLD).The purpose of this research is deriving required parameter...
