From the industrial standing point, some sorts of metal materials and reinforced plastics used as structural or insulating parts in electric and mechanical machines were studied for their damage mechanism and failure properties, and so their new strength evaluating method with considering the time and temperature-dependence was devised to be useful for life assessment as well as mechanical design. Ceramics of typical brittle body were studied for their damage mechanism and probabilistic failure properties, and so the novel unificational strength evaluating method was proposed with considering both probabilistic defect dispersion and loading duration time, and can be evaluated probabilistically many strength data obtained by different conditions of applied stress and specimen size considering with effective volume as well as effective loading duration time. Both evaluation methods can estimate, also, the temperature-dependence of strength on the basis of active process concept and had been generally acknowledged to be very valuable for science as well as engineering.
