Web1 Jul 2024 · This model establishes the relationship between the wear depth and the load, sliding distance and hardness, and it is generally given by (4)V/S=K/HF[sub.N] where V is the wear volume, S is the relative sliding distance, K is the wear coefficient, H is the hardness of the material, usually taken as H˜3s[sub.s], s[sub.s] is the yield strength of the material. WebThis article studies a new family of bivariate copulas constructed using the unit-Lomax distortion derived from a transformation of the non-negative Lomax random variable into a variable whose support is the unit interval. Existing copulas play the role of the base copulas that are distorted into new families of copulas with additional parameters, allowing more …
