We are extremely well equipped to break stuff and measure the stresses involved to a high degree accuracy.  Our biggest and strongest machine is our ATS Series 1620 20,000 lbs. capacity universal testing machine.  From their lips to our web page:

“Our electromechanical Universal Testing Machines are capable of performing virtually any test on almost any material when coupled with our unmatched line of standard and custom testing accessories.  As with all ATS equipment, any of our standard frame designs can be custom-modified by our experienced Engineering department to suit any application or space restriction.”  We agree; here’s an up close look at ours putting a wood joint through it’s paces:

Next up we have a servo hydraulic Axial Fatigue Test machine from the fine folks at Testresources.  Ours is a model 910LX15 – 3,300 lb capacity.  As the folks at Testresources say, more or less:

“Servo hydraulic test machines typically produce high loads at high test speeds compared to all electro mechanical and electro dynamic test machines. 910 Series test systems are used for product and material tests and include a dual column load frame, servo hydraulic actuator with servo valve, fatigue rated load cell, hydraulic power pack, digital controller and test software.  The 910 includes a high efficiency variable frequency drive servo pump and a servoactuator that includes a high resolution digital encoder, capable of micron level control. Actuators are available with speeds to 100 hz and forces to 5500 lb (25 kN). The popular 910 series includes all items needed. ”
