It is well known that the temperature variation associated with deformation of rubbers is mainly due to the Gough-Joule effect. However, quantitative evaluation of the temperature variation of rubbers under cyclic loading has not been studied very well. In this study, temperature variation of a chloroprene rubber subjected to uniaxial tensile cyclic loading is studied. The three-chain model is modified to describe the Mullins effect and residual strain under cyclic loading. The parameters of the model are identified experimentally at each loading condition. The temperature amplitude due to the Gough-Joule effect is predicted based on the modified three-chain model. The predicted temperature amplitude is compared to the temperature amplitude measured with an infrared thermography. As a result, it is shown that the prediction matches well with the experimental result.
