27-82 INFLUENŢA FENOMENELOR DE ECRUISARE ŞI ÎMBĂTRÂNIRE ASUPRA MODULULUI DE ELASTICITATE


THE INFLUENCE OF COLD-HARDENING AND AGING
ON THE COEFFICIENT OF ELASTICITY
Existing industrial steel structures, and especially those we use in the steel industry, for whom the normal operation age is approaching completion, are affected by the phenomena of cold-hardening and aging of steel. Depending on the size tension (unit stress) and the period of running, this paper is intended to adopt a different coefficient of longitudinal elasticity corresponding to components of the resistance structure.
Keywords: hardening, artificial aging, elastic modulus, strength, tension (unit effort)
Cuvinte cheie: ecruisare, îmbătrânire artificială, modul de elasticitate, rezistenţă mecanică, tensiune (efort unitar)
