SYSTEM FOR CALCULATING PLASTIC STRESS INTENSITY FACTOR

摘要

A plastic stress intensity factor calculation system for calculating a plastic stress intensity factor for a structure in which plastic deformation occurs to which a mechano-luminescence (ML) paint is applied is disclosed. The plastic stress intensity factor calculation system receives images of the structure from the imaging unit and the imaging unit, calculates the cumulative pressure light emission intensity from a preset initial time to the present, and generates a cumulative pressure intensity image, and the cumulative pressure light An image processing unit that analyzes an isometric intensity image to extract information necessary for calculating the presence or absence of a crack in the structure and the plastic stress intensification factor, effective stress information according to the cumulative compression intensity for the structure, and the structure A storage unit for storing information on the material constant of; And a plastic stress intensity factor of the structure using information provided from the image processing unit and information stored in the storage unit ( ) Is provided with an operation processing unit that calculates.
