From the viewpoint of continuum mechanics, cohesive and adhesivefracture have been shown to be similar. The energy approach to adhesivefracture has provided a method of interpreting the results from a convenient “blister” test that may be used quantitatively to evaluate bond strengths for particular bi‐material bond systems. Inquiring further into adhesivefracture, the effect of including an elasticadhesive interlayer between the two other materials is investigated analytically and experimentally. The experimental system is typical of the propellant‐liner‐steel combination frequently encountered in a solid rocket motor.
