Viscoplastic Response of Structures for Intense Local Heating
Publication: Journal of Aerospace Engineering
Volume 7, Issue 1
Abstract
A thermoviscoplastic finite element method employing the Bodner‐Partom constitutive model is used to investigate the response of simplified thermal‐structural models to intense local heating. The computational method formulates the problem in rate form and advances the solution in time by numerical integration. The thermoviscoplastic response of simplified structures with prescribed temperatures is investigated. With rapid rises of temperature, the nickel alloy structures display initially higher yield stresses due to strain rate effects. As temperatures approach elevated values, yield stress and stiffness degrade rapidly and pronounced plastic deformation occurs.
