Study on Tensile Shear Strength of Dissimilar Lap Joints for Multi-Material Structures

In order to design a future multi-material car body, both an appropriate selection of the advanced materials and suitable assignment joining methods are essential technologies, where data-base joint performance has be prepared. this research various dissimilar lap joints were fabricated tensile shear strength those was evaluated. The used ultra-high steel (UHHS), carbon fiber reinforced thermo-plastic (CFRTP) aluminum alloy A5083P-O. resistance spot welding (RSW) refill friction stir (RFSSW) employed for UHHS A5083P-O, while & CFRTP A5083P-O by (FSSW) laser irradiation assistance plastic (LIAPW). joined RFSSW found almost two times that produced RSW, difference seems mainly caused area. area also affects or &CFRTP made FSSW LIAPW, LIAPW larger than FSSW. Moreover, all tests suggest total heat input during process might not influence proportionally relationship between conditions evaluated using artificial intelligence technologies in contribute performance.
