"Tangent Modulus in Numerical Integration of Constitutive Relations and its Influence on Convergence of NR Method" . "For the numerical solution of elastoplastic problems with use of Newton Raphson method in global equilibrium equation it is necessary to determine the tangent modulus in each integration point. To reach the parabolic convergence of Newton Raphson method it is convenient to use so called algorithmic tangent modulus which is consistent with used integration scheme. For more simple models for example chaboche combined Hardening model it is posible to determine it in analytical wax."@en . . "Poruba, Zden\u011Bk" . "RIV/61989100:27230/09:00020229" . . . . .
