Crushing and fragmentation of brittle spheres under …

2004-6-25 · Brittle spheres are crushed and fragmented between two rigid platens dynamically. More than 140 plaster spheres with two different strengths (37 and 59 MPa) and three different sizes (50, 60 and 75 mm) were tested. The impact energies varied from 10 J to over 300 J with impact velocities ranging from 1 to 9 m/s.

CZone analysis

2016-9-21 · A combination of crushing and brittle failure is predicted by the model. As the front face of the cone makes contact with the rigid surface, it exhibits brittle failure, peeling along the edges that join it to the side walls. This exposes new edges to a crushing interaction with the rigid surface.

MAXIMUM EFFECTIVE PRESSURE DURING …

Abstract. After presenting a brief review of the ductile and brittle modes of ice crushing against a vertical structure, the discussion is focused on estimation of maximum forces (or effective pressure) during continuous brittle crushing by the use of a correlation length parameter and statistical arguments.
