A simplified model of f.c.c., b.c.c., and diamond crystalline structures is used to obtain a dependence of the ideal cohesive strength on some easily measurable quantities. The proposed conception is physically more justified as the well known Kelly‐Orowan approach. On the basis of the relationship between cohesive energy, bulk elasticity modulus, and atomic concentration, a very simple expression for the approximative determination of the ideal strength can be found.
