A direct assessment of creep life based on small punch creep test

•Two direct creep life assessment will be introduced for SPCT.•Equivalent formulation are proposed to convert multiaxial state into uniaxial.•A correction factor is defined to account for friction effect on contact surface.•A case study successfully demonstrates the proposed method in comparison wit...
