... modulus was also found to increase overall with age, increasing by > 100 % between P10 and adult rats. Unconfined compression tests ( ε = − 0.3 ) were performed on whole slices of the hippocampus and cortex of P10, P17, and adult rats to verify the mechanical properties measured with the AFM. Mean...

... in the contact pressure, decreases in the contact area, and shifts of the contact area are all believed to be related to the genesis of the disease ( 2 ). Hence, the study of tibiofemoral contact is a subject of importance in understanding the etiology of OA. biomechanics bone compressive testing...

Stepwise compression loading was also conducted on a single porcine vertebra and the loading data was compared to results obtained from an industrial grade compression testing machine. Finally, micro-CT scans of a porcine vertebra prior...
