    Abstract:

    This paper is focus on mixed failure mode which is one of failure modes in clinch joint. At presentꎬ
    there is no clear definition of mixed failure mode in any published paper.This paper offers the conception of mixed fail ̄
    ure mode and analyzed the situation which mixed failure mode would happen.Mixed failure mode often appears in the
    situation that the sheets with good mechanical propertiesꎬ great material flow and prefect parameter of clinched joint
    section.Load ̄bearing capacity and buffering capacity of 1420 and TA1 hybrid clinched joint’ s three different failure
    modes could be compared directly from force ̄displacement curves and energy absorption.The result showed that mixed
    failure mode had excellent performance because it showed characteristics both from neck fracture and button separation
    mode
