Determination of the Young's modulus of coke – a novel method

Abstract

Based on the Hertz contact problem of two cylinders a method was developed to determine Young's modulus of brittle materials, e.g. coke, from the indirect tensile test. The error band to be taken into account for evaluation have been discussed. As far as chamber‐oven cokes are concerned, it was possible to derive Young's moduli, which correlated well with the values found by other authors by means of static measuring methods. In addition was determined, on a semi‐empiric basis, a linear relation between Young's modulus and porosity, – relation allowing to consider the influence of coke structure as well.

FEM numerical analysis of the compaction of a mixture of brake pad components taking account of the real shapes and dimensions of particles

“…The numerical simulations of powder compaction were carried out for a mixture containing components T a b l e 1. The basic mechanical properties of the particle materials [29][30][31][32][33][34][35] Yield of the brake pad. The ratio between the filling height of the mixture and the height of the finished product is 2.4 to 1, so the volume fraction of air in the powder mixture is about 58.3 %.…”
