The invention provides a test method for quantitatively studying a stress wave propagation law of a porous rock, which adopts a dynamic true triaxial electromagnetic Hopkinson bar test system for testing. The test method comprises: quantitatively designing and preparing a cubic porous rock sample required by testing; placing the cubic pore rock sample in a central cubic square chest; and quantitatively studying a high-amplitude stress wave propagation law of the porous rock on the cubic porous rock sample by adopting the dynamic true triaxial electromagnetic Hopkinson bar test system.

A wire bond pull test apparatus for detecting a bond failure or wire breakage during a vertical tensile strength testing of a bonded wire under test. The test apparatus has a clamp structure with clamping elements and a controllable actuator coupled to at least one the clamping elements and configured to drive the movement of the clamping elements relative to each other to clamp the wire under test.
