DIRECT AND INVERSE PROBLEMS FOR AN INHOMOGENEOUS MEDIUM
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2019, Vol 64, Issue 1
Abstract
The plane problem for an inhomogeneous medium is analyzed in this paper by using the cnoidal representation of the material inhomogeneity. This representation approximates the distribution of elastic properties in the material. Direct problem is finding the stress distribution in an inhomogeneous body when the elastic moduli of the material are known, and the inverse problem is searching for the elastic moduli of the inhomogeneous material for a given state of stress. The inverse problem is exercised to an inhomogeneous shallow shell subjected to uniformly distributed external load.

USE OF GENETIC ALGORITHMS FOR FITTING THE BOUC-WEN MODEL TO EXPERIMENTAL HYSTERETIC CURVES
In this paper a Genetic Algorithms (GA) method is developed to identify the Bouc-Wen model parameters from the experimental data of periodic loading tests. It is considered an extension of classical model in order to inc...
INVARIANT CHARACTERIZING THERMALLY ACTIVATED PLASTIC FLOW
Thermal activation leads to a reduction of the flow stress below the athermal value (the zero Kelvin flow stress). The ratio between the flow stress at a given temperature and the athermal stress (at given material struc...
