Carbon fiber-reinforced plastic (CFRP) is a lightweight material that can potentially replace structural steel components in automobiles. The hole-clinching process mechanical clinching technique for joining brittle or low-ductility materials, such as CFRP, with ductile materials. In this study, the influence of tool shape on CFRP and SPRC440 was investigated using FE-analysis experiments. parameters were punch corner radius diameter. geometrical interlocking shapes hole-clinched joints...
Recently, carbon fiber reinforced plastic (CFRP) with high strength, stiffness, and lightweight is used widely in number of composite applications such as commercial aircraft, transportation, machinery, sports equipment. Especially, it necessary to apply materials car components for reducing energy consumption CO 2 emissions. In case roof reinforcement manufactured using CFRP, superior strength bending stiffness are required the safety drivers rollover accident. Mechanical properties CFRP...
In general, cylindrically curved plates are used in ships and offshore structures such as wind towers, spa structures, fore aft side shell plating, bilge circle parts merchant vessels. a number of studies, it has been shown that curvature increases the buckling strength plate under compressive loading, ultimate load-carrying capacity is also expected to increase. present paper, series elastic elastoplastic large deflection analyses were performed using commercial finite element analysis...
Accurately predicting the strip profile after thin-foil cold rolling is very difficult because of thinness strip. In this study, a three-dimensional (3D) model was developed to improve accuracy rolled profile. The distribution contact pressure between rolls (i.e., work, intermediate, and backup rolls) work roll were calculated by using geometric structure 6-high mill boundary conditions imposed in width direction numerical method. determined Fleck's rolling. 3D rolled-strip predicted...
The objective of this study was to design the die groove profile and predict rolling force produced when employing variable curvature rolls mandrel for manufacturing seamless pipes using cold pilger process. parameters key process were diameter initial tube final product, as well feed amount, reduction area, principal deformation zone, roller radius. forces during theoretically calculated enable their prediction, characteristics identified. values in close agreement with experimental data....
