Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but many

• The peak stress is the strength of the rock. – It may fail astrophically if the load frame is "soft". Example below is for a "stiff" frame. • The compressive strength of rock is a function of the confining pressure. • As the confining pressure increases so does the strength.
