Abstract

La invencion proporciona un metodo de adaptacion de una barra de metal, para su uso como perno para roca, para garantizar que se rompera la barra de una manera predecible, incluyendo el metodo la etapa de retirar material de la barra en una banda circunferencial para reducir el diametro de la barra dentro de la banda hasta un diametro menor para proporcionar de ese modo una zona de fallo dentro de la cual se rompera la barra si se somete a una carga de traccion suficiente.
