Polyvinyl Alcohol (PVA) hydrogel plugs were implanted in artificial osteochondral defects on the trochlear groove of rat knees. After 0, 3, 6, 12, and 24 weeks of followup, samples containing the implants were mechanically evaluated by creep indentation test, chemically, and histologically by optical microscopy. The mechanical test pointed towards an increase of the implant creep modulus and th...

Polymer materials have been used in a wide area from our homes to industry today. For this reason, creep curves the mechanical properties of polymer are an important factor for correct use polymers. This article presents new constant load test machine design which is mechatronic system perform testing A low-cost was developed by mounting clamps, pulleys, weights and steel cable on top main fram...
