Good Agreement

In the context of automotive crash simulation, rate-dependent properties are sought for all materials undergoing deformation. Measuring rate-dependent properties of adhesively bonded joints is a challenging and associated with additional cost. This article assesses the need for having rate-dependent properties of adhesively bonded joints for the example of a typical automotive structure, an adhesively bonded metallic T-joint. Using Finite Element simulation it could be shown that good agreement between experiment and simulation was only achieved if rate-dependent properties were considered for the adhesive.

Erichsen Cupping Test

In this paper the formability of heat treated AA19000 and AA5052 aluminium alloys was studied through experimentation and finite element simulation. The aluminium alloys of 1mm thickness as received and annealed condition were subjected to tensile test and Erichsen cupping test. The experimental results showed that AA5052 possessed better formability than AA19000, due to its magnesium content. The material properties obtained from the tests were validated through simulation using ABAQUS/CAE.

Bonding Property

Resin mineral composite (RMC) reinforced by fibers belongs to a multiphase material, whose mechanical strength depends on its material properties of components and microstructure characteristics of fibers including surface state, shape, and so on. The interface mechanism between fiber and matrix was analyzed. Finite element simulation was employed to discuss the reinforced effect of fiber on resin matrix, and the influence of fiber shape, surface state on interface bonding property respectively. Research results showed that linear fibers with surface dents or fibers shaped like S, U, V, N, W English letters performed well, and had much better reinforced effects on matrix than ordinary linear fibers.

Element Simulation

Extending extrusion process of semisolid AA2017 alloy was achieved. Metal flow during the process was analyzed by the finite element simulation. It was shown that alloy flow velocity decreases gradually from the center part to the sides of the mould, sometimes a transitional turbulence region appears in the middle. A smaller declining angle θ and without step d is suggested in the design mould. Alloy flow velocity at the center of the forming region decreases linearly with increases of the extending ratio s1/s0.
