| 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. |
