Force load displacement and initial cavitation point of soft adhesive under tension shear coupling load

By changing the angle of the diagonal joint, complex loads with different tension shear coupling ratios were applied to the soft adhesive layer. The experimental angles of the joint angles were 0 ° (lap shear), 20 °, 30 °, and 45 °, respectively.

Combined with real-time observation equipment, a 10 micron resolution micro camera was used to capture the soft adhesive in real time. The mechanical response points corresponding to cavitation were marked on the mechanical curve for the first time under different tension shear coupling states. The loading rate of the stretching machine is set to 1mm/min.
