description This study presents the findings determine of a comparative study to indirect tensile strength from H-Ometer test and finite element method.

The relationship between indirect tensile strength of the H-Ometer Test and Finite Element Method for weathered mudstones are presented. The H-Ometer results on axial model specimens showed the average indirect tensile strength is 0.102 MPa and the finite element analysis is 0.116 MPa.
