Abstract : Strength, elastic properties, load duration and creep were measured following exposure to temperatures and stresses expected during service life. Temperature-stress exposure reduced strength properties. High testing temperature reduced strength and low temperature raised strength. Shear elastic modulus was quite stable in the range 10 to 160deg F (-12 to 71deg C) but increased markedly at lower temperatures. Long time loading caused a larger strength reduction for the adhesive than we expect to observe for wood. This load duration effect was larger at elevated temperature. Adhesive creep was similar to wood creep but greater at 70deg F (21deg C), increasing more at 160deg F (71deg C).
