In this paper, two types of bolted joint with plastics bolt, Type I and Type 2,are examined for the purpose of absorbing the energy in the joints. The bolt is made of polycarbonate(PC) and its size is M 12. The clamped members of the both joint types are composed of a cylinder and a steel crosshead. The cylinders of Type 1 and Type 2 are made of PC and steel respectively and for Type 2,O-ring is attached to the crosshead. The relations between the allowable energy and the corresponding tightening force in the both joint types are derived and compared with the experimental results. As the result, obtained conclusions are summarized as follows : (1) When the residual pressure required on the bearing surfaces in a joint is relatively low, Type 2 is superior in energy absorption to Type 1. (2) When the residual pressure required exceeds a certain value, energy absorptivity between these two types is reversed. (3) Maximum allowable energy and the corresponding optimum tightening force could be predicted fairly well by use of simple calculation method proposed in this article.
