Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 3,   Pages 605-617 doi: 10.1007/s11709-018-0499-x

Abstract: It is shown that, in cases of low wind speeds, the IF-denoted model reflects correctly the mean windload properties, and results in correct mean structural responses; in contrast, the RF-denoted modelAt very high wind speeds, however, even the IF-denoted model can lead to significant deviation from theTo solve the incompatibility at high wind speeds, a methodology of subtraction of pseudo-steady effectsfrom the aeroelastic model is put forward in this work.

numerical simulation on compressive buckling behavior of thin steel skins in unilateral contact with rigid

Nicholas KEAGE, Christopher MAIOLO, Rebecca PIEROTTI, Xing MA

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 3,   Pages 335-343 doi: 10.1007/s11709-011-0121-y

Abstract: In this paper, a practical test and finite element analysis has been undertaken to further investigate the effects of contact buckling. A test rig was designed and constructed to record vertical and transverse deflections of compressively loaded steel skin plates. The boundary conditions were modeled as fully fixed. A finite element analysis was also undertaken using the software package Strand7. Results from both analyses have been examined and compared to data established from previous studies on contact buckling. Both the finite element analysis and practical results correlate well with this data. The result of the investigation has confirmed contact buckling theories and has foreshadowed the onset of the newly observed phenomenon of secondary contact buckling.
