This step enables for the first time to apply the principles of fracture mechanics to all disciplines dealing with confined particles comminution such as geophysics, geology, geotechnical engineering, mineral processing, agriculture and food industry, pharmaceutics and powder technology. This critical pressure is surprisingly complementary to Griffith's critical tensile stress for near-continuous materials. Here I establish this relation using energy principles and derive a critical comminution pressure for brittle granular materials. However, the analogy between the mechanics of breakage and fracture is missing. Recently, I have developed an energy theory, called breakage mechanics, based on the concept of breakage. Nothing similar was developed for brittle granular matter, although in these materials fracture propagates in the sense of comminution. In a very succinct way, Griffith connected between three important aspects of the fracture process: (i) the material, (ii) the stress level, and (iii) the geometry of the crack. Fracture (2007) Plot Showing all 7 items Jump to: Summaries (6) Synopsis (1) Summaries An attorney intending on climbing the career ladder toward success finds an unlikely opponent in a manipulative criminal he is trying to prosecute. Needless to say that his celebrated work has revolutionized the world of material science. A husband is on trial for the attempted murder of his wife, in what is seemingly an open/shut case for the ambitious district attorney trying to put him away. It is nearly a century since Alan Arnold Griffith developed his energy criterion for the fracture propagation of cracks in ‘near-continuous’ solids. AKA:, Fracture 2007, Das perfekte Verbrechen.
