Biomechanics Lab Resources
Dynamic Mechanical Analyzer
The DMA applies cyclic stress to a sample to measure its elastic and viscous material characteristics
ABAQUS and Patran Finite Element Software
Industry standard programs used for 2 or 3-dimensional theoretical static or dynamic stress analysis
We have a variety of transducers that are used in custom applications. These include: LVDTs, potentiometers, DVRTs, pressure transducers, extensometers, and load cells.
MTS 420/Instron 1321/MTS 858 Mini Bionix II Servohydraulic Biaxial Testing Machines
Used for experimental material testing and high cycle fatigue studies
Micro Mechanical Tester
The micro tester is composed of a load cell and a linear servo motor mounted on an inverted microscope. Mechanical tests such as tension and stress relaxation are applied to measure mechanical properties of biological samples such as tendon or muscle fibers.
Range of Motion and Dislocation Simulator
We developed an automated range of motion simulator and dislocation testing device for evaluating the range of motion and stability of a joint undergoing osteotomy, arthroplasty, etc.
Spine Testing Device
Allows a pure moment to be applied to the spine for multi-segment testing.
Kinematics Testing with Polhemus Fastrak
Polhemus Fastrak can be used to measure the motions of structures with respect to one another with six degrees of freedom. This can be used to study structures such as the foot.
Gliding Resistance Tester
The gliding resistance tester can be used to test the resistance of one tissue relative to another, for example a tendon gliding beneath a pulley sheath.
Motion Analysis System
We have three Motion Analysis cameras and Eva 6.0 motion analysis software, for characterizing the motion of digit tendon or the motion of the joint prosthesis.
The MSTR Core Facility regularly supports the training of research fellows and students. This training includes methods of specimen preparation, data collection, and data analysis.
The Optotrak Certus is an active marker kinematic data collection system that is used to track the 3D motion of rigid bodies in space. It has an accuracy of up to 0.1 mm, collects at a frequency of up to 4600 Hz, and can collect data on up to 170 rigid bodies.
Mechanical prototypes and testing apparatuses can be custom designed and built in the machine shop.
