    Notes: Abstract The so-called edge problem, i.e., the traction discontinuity at edges or corners of the domain, is solved for the case of the transversely isotropic material being introduced into 3D BEM. The auxiliary relationship equations for the additional traction components are derived and the arbitrary inclination of the isotropic plane of the material is taken into account in the mean time. An example is given, and the comparison of the numerical result of the example with the theoritical solution is also illustrated.

    Notes: Buckling of compression flanges of welded I-beams consisting of more than one lamella is characterized by partial loss of contact between the lamella welded to the web and the neighbouring lamella. The boundaries of the contact regions of the buckling modes of the two lamellae are originally unknown. Thus, the present elasto-plastic plate-stability problem is coupled with a contact problem. It represents a unilateral problem because eigenforms with penetrations of lamellae are physically impossible. This problem is solved first for the elastic material domain. The Rayleigh-Ritz method is used for determining symmetric eigenforms. A finite-strip technique is employed for determining unsymmetric eigenforms. The solution of the unilateral elastic plate-buckling problems serves as the starting point for the iterative solution of the corresponding elasto-plastic plate-stability problem. The buckling pressures obtained are compared with corresponding buckling stresses resulting from a classical design procedure disregarding the interaction of the lamellae at buckling.
