Abstract

La presente invención consiste en un modelo de mordazas de confinamiento y un método para caracterizar mediante la determinación de la resistencia a la compresión, los especímenes de materiales por medio de la aplicación de compresión inconfinada en muestras con forma de disco y sometidas a cargas distribuidas diametralmente. Donde las muestras con forma de disco son muestras de roca intacta cuya relación longitud-diámetro (L/D) están por debajo de lo establecido por la norma ASTM D 4543. Las mordazas desarrolladas se caracterizan entre otras porque: el área que hace contacto con el disco tiene un contorno curvo que sigue el perfil circular del disco, presentan un par de aletas en los extremos del arco de manera que la fuerza que ejerce la prensa se distribuye de forma regular sobre toda el área de contacto de la mordaza con el disco. Las aletas presentan una terminación redondeada o en bisel para evitar deformaciones de la mordaza. La base de la mordaza también comprende unos contornos curvos que garantizan el adecuado trabajo mecánico del material para que la mordaza no sufra excesivas compresiones que puedan destruir la pieza.The present invention consists of a model of confinement jaws and a method for characterizing, by determining the compressive strength, the specimens of materials by means of the application of unconfined compression in disc-shaped samples and subjected to diametrically distributed loads . Where the disc-shaped samples are samples of intact rock whose length-diameter ratio (L / D) are below what is established by ASTM D 4543. The jaws developed are characterized among others because: the area that makes contact with The disc has a curved contour that follows the circular profile of the disc, has a pair of fins at the ends of the arc so that the force exerted by the press is distributed regularly over the entire area of contact of the jaw with the disc . The fins have a rounded or bevelled finish to avoid deformation of the jaw. The base of the jaw also includes curved contours that guarantee the adequate mechanical work of the material so that the jaw does not suffer excessive compressions that can destroy the piece.
