Результаты и перспективы работы челябинской научной школы прочнистов
Аннотация
Дано краткое описание созданных школой Д.А. Гохфельда новых научных направлений и их приложений в области анализа деформирования и разрушения материалов и конструкций при повторных (малоцикловых) воздействиях:
- прогрессирующего формоизменения при теплосменах;
- математической теории упругой и неупругой приспособляемости;
- малоциклового деформирования и разрушения хрупких (малопластичных) материалов и конструкций (в том числе – графитовых);
- сеток трещин в природных и техногенных объектах;
- дилатационных повторных воздействий внешней среды (водорода, природного газа и других);
- стабильных и нестабильных деформационных свойств сталей, сплавов и других материалов и их математического моделирования;
- неустойчивости процессов неупругого малоциклового деформирования;
- закономерностей деформирования и разрушения конструкций с циклически меняющейся структурой (в том числе – при замерзании и таянии рабочей среды).
Намечены перспективы развития исследований, связанные прежде всего с переходом от обеспечения безотказности к обеспечению безопасности, а также с расширением приложений.
