The rigidity modulus of alloy AB at temperature T and zero pressure is as follows:
Our numerical results for the thermal expansion coefficient and the heat capacity at constant pressure, the Young modulus, the bulk modulus, the rigidity modulus and the elastic constants of alloy FeC are summarized in tables from Tables 2-5 and are described by figures from

where: w [mm]--is the travel in transversal direction; q [N.[mm.sup.2]]--is the transversal load distributed onto the surface of the plate; r [mm]--momentary radius; D [mNm]--is the rigidity modulus
at cylindrical bending, given by the equation:
