Күрделі термодинамикалық жүктеме жағдайында үйкеліс кезінде түйіндесулердің контактілі бұзылуының механикасы қарастырылған. Жанасу кезінде беткі қабаттың қалыптасу ерекшеліктерін ескеруімен, үйкеліс түйіндерінің күрделі зақымдануын, тозу қарқындылығын математикалық сипаттау мүмкіндігі көрсетілген. Трибо-түйіндесулердің беткі беріктігі мен төзімділігін есептеу әдісі ұсынылған. Бұл нүктенің кернеу күйінің параметрлерін (үйкеліс коэффициенті, пішін факторы) процестің термомеханикалық параметрлерімен байланыстыруға мүмкіндік береді. Үйкеліс коэффициентінің, пішін параметрлерінің өзгеруін бағалау арқылы аққыштықтың кернеуін анықтау және берілген кернеу жағдайына сәйкес құрылымдық түрлендірулерді орнату мүмкіндігі пайда болады.
