INFRARED THERMOGRAPHY COUPLED WITH REVERSE PROBLEM AT FINITE ELMENT ANALYSIS

摘要

This paper presents a way to mix the infrared thermoghraphy with the reverse problem in finite element analysis. The infrared imaging is used to derive the instant distribution of thermal field in cutting process, so the nodal values corresponding to a predefined mesh. These nodal values, in fact solutions for Poisson equation, are introduced in a special program based on variational approach for heat transfer. This program computes the value for internal source corresponding to the measured distribution, so we can handle better the cause of thermal phenomena in cutting process.
