Abstract
ES NECESARIO EL PROCESO DE PUENTEADO A PARTIR DE UNA ALEACION DE MEMORIA DE FORMA POR MEDIO DE EL ESPACIO GENERADO EN ELASTICIDAD RECUPERADORA CON LA AYUDA DE UNA PARTE CONSTRUCTIVA ADICIONAL. SIN TENER QUE PARTIR DE ESTA PARTE CONSTRUCTIVA SE UTILIZA UN MATERIAL DE VAINA CON VALORES DE RESISTENCIA REDUCIDOS EN COMPARACION CON EL MATERIAL DEL TUBO. EN BASE A LA GRAN ELASTICIDAD RECUPERADORA DEL TUBO SE CONSIGUE UNA UNION ESTANCA.
