High strain rate testing of kidney stones.

Journal article

Sections of struvite kidney stones were tested in compression at high strain rates ( approximately 3000s(-1)) using a Kolsky bar and at low strain rates ( < 0.001 s(-1)) using an Instron testing machine. The peak stress in both cases appeared to be similar. At high strain rates the values of flow stress measured were between 40 and 65 MPa and at low strain rates they were between 37 and 58 MPa. However, the morphology of the damage was dramatically different. Stones tested at low strain ra...
