Abstract
METODO PARA DETERMINAR LOS ESFUERZOS RESIDUALES DE UN OBJETO (TENSIONES INTERNAS), MEDIANTE UNA FUSION PARCIAL DE SU SUPERFICIE. SE UTLIZA UN MEDIDOR DE DEFORMACIONES RESISTIVO DEL TIPO DE ROSETA CON TRES ELEMENTOS. CON UN HAZ CONCENTRADO DE LASER SE FUNDE UNA ZONA DE LA MUESTRA SITUADA EN EL CENTRO E LA ROSETA (15). EL CAMBIO DE RESISTENCIA Y, POR TANTO, EL CAMBIO DE DEFORMACION DE LOS TRES ELEMENTOS DEL MEDIDOR DE DEFORMACION (11, 12, 13) SE MIDE ANTES DE QUE EL MATERIAL FUNDIDO SE SOLIDIFIQUE Y ANTES DE QUE EL CALOR HAYA LLEGADO BAJO LOS MEDIDORES, SIENDO EL CITADO CAMBIO PROPORCIONAL A LOS ESFUERZOS RESIDUALES. SE APLICA AL ESTUDIO DEL INTERIOR DE TUBOS DE REACTOR SOMETIDOS A TENSOCORROSION. F
