Asymmetric Buckling of Heterogeneous Annular Plates,metrical buckling is sufficiently lower than for a plate with constant mechanical properties. For an annulus with large inner radius, the buckling pressure and the buckling mode number increases as the Young modulus decreases towards to outer edge of a plate.谁在削木头 发表于 2025-3-27 11:40:59

1869-8433 sents the various approaches in establishment the basic equations of one- and two-dimensional structural elements. In addition, the boundaries of validity of the theories and the estimation of errors in approximate theories are given. Many contributions contain not only new theories, but also new apBrain-Imaging 发表于 2025-3-28 12:03:56
