Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA CARACTERIZACION ELASTICA NO LINEAL DE MATERIALES SOLIDOS. EL OBJETO DE ESTA PATENTE ES EL ESTABLECIMIENTO DE UN PROCEDIMIENTO DE MEDIDA Y UN DISPOSITIVO EXPERIMENTAL QUE PERMITE LA CARACTERIZACION NO LINEAL DE MATERIALES MEDIANTE LA MEDIDA DE SU PARAMETRO DE NO LINEALIDAD. EL PROCEDIMIENTO SE CARACTERIZA PORQUE LAS MEDIDAS SE HACEN CON MUESTRAS EN RESONANCIA Y EL PARAMETRO DE NO LINEALIDAD SE DEDUCE DE LA GENERACION DE ARMONICOS. EL DISPOSITIVO EXPERIMENTAL ESTA CONSTITUIDO POR UN SISTEMA DE EXCITACION, UN SISTEMA DE ADQUISICION DE DATOS Y LAS MUESTRAS RESONANTES DEL MATERIAL. EL SISTEMA DE EXCITACION SE COMPONE DE UN TRANSDUCTOR PIEZOELECTRICO DE POTENCIA EXCITADO POR UN GENERADOR ELECTRONICO QUE INCLUYE UN CIRCUITO DE SEGUIMIENTO DE LA FRECUENCIA Y OTRO PARA EL CONTROL DE TIEMPO DE EXCITACION. EL SISTEMA DE ADQUISICION DE DATOS CONSISTE EN UN CAPTADOR DE VIBRACIONES Y UN TERMOMETRO NO INTRUSIVOS. LAS MUESTRAS SON BARRAS CILINDRICAS RESONANTES DE SECCIONESCALONADA CON LAS QUE SE CONSIGUE UNA GRAN CONCENTRACION DE ENERGIA, LO QUE PERMITE ALCANZAR EL RANGO NO LINEAL CON EXCITACION LINEAL.
