Abstract
Stainless steel and especially the authentic ones have been in applications for the industrial
equipment, consumer items, and architectural components amongst other things. Simulations of
the processes of manufacturing of such components and their parts needs enough hardening that
is very description and very accurate in the parameters. This paper shall be addressing all these
issues of the stainless steel with strict observations to the phenomenological approaches with a
logarithmic yields of higher orders and alternatives micromechanical-based equations. To come
up with the inelastic parameters is obtained by either optimization techniques or curve fitting
strategies. The comparative experiment-numerical assessment explains that the equation of
michrochemical-based yields is obtained from Bergstrom’s model of dislocation that gives the best
descriptions for hardening.

Introduction
Stainless steel especially the aesthetic grade of AISI 304 has been under a wide
implicational uses like in the industrial equipment like pharmaceutical, food and mining
equipment, consumer items like sink, parts and cutleries, architectural components like ornaments
and decorative panels amongst many other things. The reason is determined by how good it is in
resisting oxidation and corrosion, toughness, formability, ductility and weldability (Dahotre &
Harimkar, 2018). The higher industrial wilderness has prompted the discussion on how suitable
are they to be heuristically selected and phenomenological equations to be based on the hardening
model of the evolution of stainless steel and the processes of finding out the corresponding
parameters.
Numerical simulations if done carried out on the metals in the operations of manufacturing
components in stainless steel, they need inelastic modeling to be conducted appropriately. The
important aspects to keep in mind are the inelastic parameters and the hardening laws together
with how far plastic deformations can go. Inelastic properties can be found using either the inverse
problem techniques or the curve fitting strategies (Duriagina, 2019). The latter correlates directly
to the true strains and stress under a uniform deformations unlike the former which gains the
inelastic parameters by applications of optimization methods that are related to the global
measurers like load information and geometry.

Literature review
Literature review indicates parameters of hardening stainless steel that are determined by
the strategies called curve fitting. The strategy is associated to the tensile tests like when the
hardening of stainless steel under high pressure basing on Holloman’s
second and third
stage σ=Kεn (ε and σ are strains and stress). K is the coefficient ...
