Similarity consideration of structural bifurcation buckling [PDF]
Forschung im Ingenieurwesen, 1999 Many structural bifurcation buckling problems exhibit a scaling or power law property. Dimensional analysis is used to analyze the general scaling property. The concept of a new dimensionless number, the response number-Rn, suggested by the present author for the dynamic plastic response and failure of beams, plates and so on, subjected to large ...

Buckling Paradox And Anisotropic Plastic Plate Bifurcation [PDF]
Progress in Canadian Mechanical Engineering, 2018 Anisotropic elastic/plastic plate bifurcation is investigated. The pre-bifurcation loading consists of biaxial stresses along ξν axes parallel to the sides of a simply supported rectangular plate: ννξξσασ=,11α−≤≤. The ξν axes are at an angle βwith the xy principal axes of anisotropy.

Analysis of multiple bifurcation behavior for periodic structures
Archives of Mechanics, 2020 The classification of simple singularities in the post-buckling analysis of truss structures is well-known for elastic stability. To focus on multiple singularities including a hilltop bifurcation point (h-BP) and its bifurcation paths, we reviewed the ...

Non-bifurcation behavior of laminated composite plates under in-plane compression [PDF]
Bulletin of the Polish Academy of Sciences: Technical SciencesThe paper deals with bifurcation and/or non-bifurcation post-buckling curves of composite plates under biaxial compression. For different lay-up sequences, a coupling, i.e. extension-bending (EB) is considered. The current investigations present distinct
