Abstract

UN METODO PARA MEJORAR LA CAPACIDAD DE UN CUERPO A SOPORTAR ESFUERZO DURANTE LA ROTACION DEL CUERPO INDUCIENDO EN UN LUGAR SELECCIONADO DEL CUERPO UN ESFUERZO DE COMPRESION RESIDUAL QUE SE OPONE AL ESFUERZO TENSIL PERMANENTE PRODUCIDO POR LA ROTACION. EL METODO COMPRENDE LA ROTACION DEL CUERPO EN UNA SUCESION DE VELOCIDADES PICO AUMENTADAS EN EXCESO DE LA VELOCIDAD DE DISEÑO PARA INDUCIR UN RENDIMIENTO TOLERABLE Y ESFUERZO DE COMPRESION RESIDUAL EN CADA LUGAR QUE EXPERIMENTA UN ESFUERZO TENSIL PERMANENTE SUPERIOR QUE EL LUGAR SELECCIONADO. LA SUCESION SE EFECTUA DESDE EL LUGAR QUE EXPERIMENTA EL ESFUERZO TENSIL MAS PERMANENTE SUPERIOR POR ENCIMA DEL LUGAR SELECCIONADO AL LUGAR QUE EXPERIMENTA EL ESFUERZO TENSIL PERMANENTE INFERIOR POR ENCIMA DEL LUGAR SELECCIONADO. ENTONCES SE ROTA EL CUERPO A UN MAXIMO DE VELOCIDAD AUN MAYOR PARA INDUCIR UN RENDIMIENTO TOLERABLE Y ESFUERZO DE COMPRESION RESIDUAL EN EL LUGAR SELECCIONADO.
