Abstract The fatigue behavior of self-piercing rivet (SPR) joints joining differing thicknesses of AA6111-T4 aluminum and HSLA340 steel sheets in lap shear geometry was investigated in this paper. Crack initiation in the aluminum sheet was the dominant failure mode, while unexpected rivet shank failure tended to occur at high loading levels. Fretting wear was also observed at interface between aluminum and steel sheets as well as between the rivet and sheets under sinusoidal cyclic tension–tensi...

Abstract The fiber orientation distribution is one of the important microstructure variables for thermoplastic composites reinforced with discontinuous fibers. In this paper, the long fibers in the injection molded part are measured in detail by micro X-ray CT. A three dimensional (3D) structure of the sample is built and two dimensional images are generated for image analysis. The orientation tensor of fibers is calculated in the flow plane. It shows a symmetric distribution of fibers through t...

The fatigue behavior of self-piercing riveting (SPR) joint, joining aluminum alloy 6111T4 and steel HSLA340 sheets with lapshear geometry was investigated in this paper. Sheet crack was the dominant failure mode, while unexpected rivet shank failure tended to occur under high loading level. Fretting wear was observed at interface of aluminum and steel layers, as well as at rivet and sheets under sinusoidal cyclic tension-tension loading. An energy dispersive X-ray (EDX) analysis of fretting debr...

A computer simulation methodology is developed to model the water quenching process for engine block and cylinder head. The methodology is based on the Eulerian-Eulerian two-fluid method implemented in existing commercial computational fluid dynamics (CFD) software. Due to the complex physics involved in the phase change and mass transfer, one of the prime objectives is to search and evaluate CFD tools that are capable of modeling the water quenching processes. Then the methodology is validated ...

The fiber orientation distribution is one of the important microstructural variables for thermoplastic composites reinforced with discontinuous fibers. In this article, Moldflow is used to predict the fiber orientation distribution in an automotive component. Image analysis by MATLAB is adopted to validate the simulated results after taking pictures of fibers by X-ray CT. It is shown that the Moldflow predicts the average distribution in direction of the thickness accurately, with predicted eige...

A tangent constitutive model was developed in this article to address the nonlinear viscoplastic behavior of compound grade thermoplastic olefin (TPO). The TPO was commonly blends of polypropylene matrix, rubber, and inorganic filler. The constitutive model for TPO was obtained from the combination of the mechanical behavior of the matrix and fillers. In a multiphase material, the rate-dependent behavior of polypropylene matrix was presented by a physically based constitutive model for large str...

The deformation behavior of a thermoplastic olefin (TPO) during tensile loading has been studied by a finite element method (FEM). Dumbbell shaped specimens of the TPO were tested under various strain rates and temperatures. The test results were used to characterize the mechanical properties of this material. To capture the nonlinear rate-dependent response of the TPO, a physically based constitutive model [M.C. Boyce, D.M. Parks, A.S. Argon, 1988] for large strain deformation was used. The mod...
