According to the popularization of higher education and the increasingly severe situation of undergraduate employment, the paper presents some education methods in the process of graduation design in order to let undergraduates, in the last phase of education, gradually adapt the future employment. Through enriching the sources and the implementation modes(More)
The paper presents a calculation method for displacements of 0° and 90° winding angle circular and noncircular cross-section beam under tensile and bending loads. The method is dividing a beam into finite beam elements, analyzing the displacements, strains and stresses of the beam elements, through the transformation of coordinates,(More)
the paper presents a failure analysis method of carbon/epoxy composite loops with the assistance of computer. The composite loops wrapped around metal pins form a kind of mechanically-fastened joint by filament winding technique. As are well known, mechanically-fastened joints under tensile loads generally fail in three basic modes, referred to as(More)
Subject competition has an important significance in many aspects, ranging from constructing discipline, course and laboratory of university, guiding universities' paying attention to educating students' the abilities of innovation, cooperation, integrating theory with practice, hands-on and engineering, sponsoring the competence-oriented education in an(More)
