ANALYSIS AND OPTIMISATION OF DESIGNS AND BOILERS WITH TUBE-IN-SHEET SHIELDS Russian patent published in 2015 - IPC G06N7/06 

FIELD: physics.

SUBSTANCE: this process is realized in steps that follow. First, shield changed structure us shaped to orthotropic plates and/or shells to calculate their dimensional, physical and mechanical characteristics. Finite-element model of said structure is developed to simulate its strained state and to analyze and to optimize its structure. Local areas of orthotropic plates and/or shells are defined at increased displacements, strains and stresses. At second step, second changed structured is formed by sections of plastic screens at local area of orthotropic plates and/or shells with increased displacements and strains. Solid-state models of said structure is developed to simulate its strained state and to analyze and to optimize its structure.

EFFECT: lower labour input in analysis and optimisation, accelerated calculations at evaluation of hardness, stiffness and stability.
