Methods for calculating the behaviour characteristics of the condition of the model of strength of resistance spot welded joints

Abstract

The role of the behaviour characteristic in the development of a mathematical model is examined. The maximum compactness method and the least squares method used for determining the characteristics of the behaviour of the mathematical model are compared.

Keywords:

• Mathematical model
• position and dispersion behaviour
• methods of maximum compactness, least squares, least modules
• inadequacy error and approximation errors
