1. A test fixture for mechanically testing breast implants comprising:
a frame;
a base plate coupled with said frame, said base plate having a first major surface;
a first actuator coupled with said base plate for providing reciprocating motion to said base plate along a first axis;
a compression plate coupled with said frame and opposing said base plate;
a second actuator coupled with said compression plate for providing reciprocating motion to said compression plate along a second axis that intersects the first axis;
a third actuator coupled with said compression plate for providing reciprocating motion to said compression plate along a third axis that intersects both the first axis and the second axis;
a control system in communication with said first, second, and third actuators for controlling the movement of said base plate along the first axis and the movement of said compression plate along the second and third axes;
wherein said base plate has two or more fixation points accessible at said first major surface of said base plate that are configured for securing a breast implant over said first major surface of said base plate.
