SysweldHow to collect data for welding simulation? Contents Introduction List of Data needed for welding simulation on steel? How to collect Material DB By Using SYSWELD Material DB By Performing Experimental Tests Dilatometer tests Tensile Tests Creep Teets Others …. Introduction Thermal, Metallurgical and Mechanical Characteristics To Find these data 3 possibilities are offered : Use the SYSWELD Material Data Base Find these Data in the bibliography Perform experimental tests to characterize all these thermal, metallurgical and mechanical Data SysweldList of needed data for welding simulation Material Properties for Steel - f(T,z) Thermal properties in function of temperature (T°c) and according to the considered phases (zi) Thermal conductivity : ? = f(T°c, zi) Density : ? = f(T°c, zi) Specific heat : Cp = f(T°c, zi) Enthalpy : H = f(T°c, zi) Latent Heat Effect : ?H = f(T°c, zi) Metallurgical Kinetics of Transformation for different speed of heating and cooling Austenitic Transformation : Z? = f(T °c, dT/dt) Ferrite Transformation : Z?f = f(T °c, dT/dt) Bainite Transformation : Z?b = f(T °c, dT/dt) Martensite Transformation : Z?m = f(T °c) Material Properties - f(T,z) Mechanical properties in function of temperature (T°c) and according to the considered phases (zi) Young’s modulus : E = f(T°c, zi) Poisson coefficient : ? = f(T°c, zi) Thermal strains : ?th = f(T°c, zi) Volume variation due to metallurgical transformations : ?V/V = cst Yield stress : ? = f(T°c, zi) Strain hardening : h = f(T°c, zi) Viscous parameter (optional for viscoplastic simulation) Hardening Coefficient : K = f(T°c, zi) Hardening Exponent : m = f(T°c, zi) Strain Rate Sensivity Exponent : n = f(T°c, zi) SysweldHow to collect these data? Sysweld Material DB By using the SYSWELD Material Data Base This data base Covers the main commercial steels and aluminums for welding and heat treatment Contains all Thermal, Metallurgical and Mechanical characteristics Has b
