A spiritual practice

Impact tests and impact grinding may subject the specimen to both tensile and compressive forces.

At a time to failure of 100 [[micro]seconds], which is comparable to the time scale for deformation during impact grinding, the brittle-ductile transition for PVC is estimated to be about 12 [degrees] C for PVC and -35 [degrees] C for PET.

Impact grinding experiments were done on chips from post-consumer bottles of PVC and PET.
