Energy and Approximate Methods,etween the energy and the differential equation approaches through the principle of virtual displacements and through various extremum principles. However, we will not pursue this connection, since it is beyond our immediate scope.EXULT 发表于 2025-3-28 23:22:16
Bending of Plates, or, with transverse shearing strains suppressed, as equations (5.55). Taken together with the stress resultant-strain relationships in the form of equation (6.10), the requisite boundary conditions discussed in section 6.2, and specifically the Kirchhoff conditions equations (6.25) and (6.27), theparsimony 发表于 2025-3-29 03:23:52
