superplastic materials show a very high ductility. this is due to both peculiar process conditions and material intrinsic characteristics. however, a number of superplastic materials are subjected to cavitation during superplastic deformation. evidently, extensive cavitation imposes significant limitations on their commercial application. the deformation and failure of superplastic sheet metals...

A series of physical modeling tests were conducted by means of a beam type geotechnical centrifuge machine in order to investigate the drainage impact on the slope failure mechanism under centrifugal acceleration. Meanwhile, the phenomenon of stress redistribution in undercut slopes and the formation of arching effect were studied. For this purpose, a poorly graded sandy soil (Silica sand No. 6...

Normal failure or risk analyses procedure contains the following steps: 1) modeling process, 2) assessment process of its hazardous extent. 1) Modeling process is the considering procedure that sets the sequence of happening failures or risks. 2) Assessment process is the evaluation procedure that express its hazardous extent quantitatively or qualitatively (probability, seriousness of injury e...

Abstract. In the numerical simulation of mechanical joining technologies such as clinching, material modeling parts is major importance. This includes damage and failure behavior materials in accordance with varying occurring stress states. paper presents a calibration method three different fracture models. The models done by use experimental data from modified punch test, tensile test bulge o...

Abstract. The application of the mechanical joining process clinching allows assembly different sheet metal materials with a wide range material thickness configurations, which is interest for lightweight multi-material structures. In order to be able predict clinched joint properties as function individual manufacturing steps, current studies focus on numerical modeling entire chain. It essent...
