    Abstract: In this study, an inverse algorithm based on the conjugate gradient method and the discrepancy principle is
    applied to estimate the unknown time-dependent frictional heat generation for the tribosystem consisting of
    a semi-infinite foundation and a plane-parallel strip sliding over its surface, from the knowledge of
    temperature measurements taken within the foundation. It is assumed that no prior information is available
    on the functional form of the unknown heat generation; hence the procedure is classified as the function
    estimation in inverse calculation. Results show that an excellent estimation on the time-dependent heat
    generation can be obtained for the test case considered in this study. The current methodology can be applied
    to the prediction of heat generation in engineering problems involving sliding-contact elements.
