Materially Efficient Thermomechanical Study Procedure for Rocks Presented on a Glauconitic Sandstone

Proper thermomechanical study of a rock type is typically significantly more expensive than a standard mechanical study in terms of geomaterial consumption. Multiple specimen sets (each sufficient for a standalone mechanical study) have to be produced for various target temperatures to obtain a comprehensive thermomechanical profile of the rock type. A possible solution for lowering the number of required specimens using a type II “multiple failure state” triaxial test is tested in this paper.
