The study of novel biomaterials and tissue-engineered products remains at the forefront of research around the world. Hard tissues such as bone, dentin, and enamel; soft tissues such as tendons, ligaments, skin, muscles, and arteries; and scaffolds such as hydrogels are all examples of tissue engineered materials or biomaterials. These materials require mechanical testing often in an environment to mimic physiological conditions to understand and characterize force and displacement properties. Mechanical testing of biomaterials typically entails a multitude of tests that include: monotonic tension, compression, or flexure tests, simple cyclic tests, creep, stress-relaxation, and dynamic fatigue tests.

Parenteral products contained in vial package systems require a robust seal at the interface between the glass vial and the elastomeric closure to prevent contamination and product leakage. The seal is established in the manufacturing process, but must withstand a variety of handling, processing and storage conditions.

During normal patient activity, spinal constructs can be subjected to high in vivo loading that can result in catastrophic failure. Spinal injuries often occur due to rotation, dislocation, bending, and axial loading

Sutures are widely used in the biomedical industry. They are used in a variety of surgical procedures to allow for wound closure and aid in tissue healing. Sutures are manufactured from various different absorbable and nonabsorbable materials, and may be single filament or braided with or without a coating. There are some challenges in testing sutures. Loading the specimen alone can pose problems as some sutures are delicate and require a low amount of force to fracture. Also, some sutures are used inside wounds and are constantly in a hydrated environment.

Surgical tubing is used in a wide variety of applications, such as drains, feeding tubes, irrigation and surgical procedures, and therefore comes in many shapes and sizes. The mechanical performance of the material used is critical, as failure could seriously endanger a patient. Tensile tests are frequently performed in product development and quality control to evaluate properties of material strength and strain at break.
