Abstract:This paper is focus on the mechanical properties of similar and dissimilar clinched joints in 1420 alu鄄
minum鄄lithium and titanium alloy sheet materials. Load鄄bearing and buffering capacity are the main standards which
could assess quality of clinched joints. Force鄄displacement curves and energy absorption drawn from the test could get
load鄄bearing and buffering capacity indirectly and also show that TA1-1420 joint owns great mechanical properties.
Besides, compared with TA1-TA1 joint, TA1-1420 joint爷weight is lighter because of its lighter lower sheet. Results
showed that TA1-1420 joint is more suitable for the part which require higher load鄄bearing and buffering capacity
