This paper examines the simulation of the motion of three power cables (three-dimensional nonlinear beams) which are constrained to move within a pipe under thermal loads. The cables are represented by beam segments which are initially straight between modes; a bilinear constitutive equation is used and changing geometry is accomodated. An example is included. Applications to the pheneomenon of thermo-mechanical bending are covered.
