Use of ultrasonic velocity travel time to estimate uniaxial compressive strength of granite and schist in Malaysia

The uniaxial compressive strength (UCS) is one of the most common mechanical parameters required in geotechnical engineering to characterize the compressive strength of rock material. Measurements of UCS are expensive, time consuming, destructive and thus, not favorable in the presence of limited sa...

The uniaxial compressive strength (UCS) is one of the most common mechanical parameters required in geotechnical engineering to characterize the compressive strength of rock material.

The validity of the practical approach presented in this research is confirmed based on the strong correlations developed from the experimental tests conducted.
