原始语种摘要: The creep behavior of a new type epoxy resin adhesive which is room-temperature cured and used for reinforcing engineeringstructures was studied. The tensile strength of the adhesive has reached the desired values for the structural adhesive usedfor bonding concrete as the base material with steel. The short-term creep tests were conducted under four different stresslevels. The generalized curve for reference stress was obtained by utilizing the time-stress equivalent principle. Moreover,compared with traditional Burgers model, an improved fractional KBurgers model obtained by replacing the Newton derivativewith the fractional derivative element (Abel component) in the traditional Burgers model can capture the creep behavior ofthis epoxy adhesive with high precision in the condition of...
