- •
Temperature effects on the behavior of Colorado shale were investigated.
- •
Strength envelopes were nonlinear with material weakening at high temperatures.
- •
A simple non-isothermal criterion was proposed to describe strength envelopes.
- •
Constitutive thermo-mechanical features of the material behavior were described.
- •
Post-peak deformations were shown to be governed by the smooth shear plane.
