A planar finite element formulation for corrugated laminates under transverse shear loading

Free-edge effects of corrugated laminates

“…The peculiar vibration behavior of corrugated laminates was studied by Thurnherr et al [12], Malikan et al [13] and by Nguyen et al [14]. A planar FEM formulation for simulating the response of corrugated laminates to transverse shear line force was developed by Filipovic and Kress [15]. The question of how to manufacture high-amplitude corrugated laminates with circularsections corrugation shape was addressed by Filipovic and Kress [16].…”

Thin-shell-theory solutions for the static structural response of circular-sections shaped corrugated laminates

“…Xia et al [36] and, later, Park et al [37] found homogenization models for thin laminates and arbitrary corrugation shapes that are also restricted to symmetric crossply laminates. Filipovic and Kress [38] have developed a planar finite-element formulation for simulating transverse-shear response that serves as an homogenization model for substitute-plate transverse shear stiffness. In summary, the existing homogenization models for predicting the structural properties of unconstrained corrugated sheets can be subdivided into two groups; namely analytical models and planar finite-element models.…”

“…Table 2 synthesizes the changed boundary conditions for each relevant load case. Subsequently, the line loads in shell coordinates (37) and in Cartesian coordinates (38) are determined. The substitute-plate properties are defined as the ratio between the Cartesian reaction forces (the line loads in xyz coordinates) and the imposed prescribed deformation (39).…”

Predicting global strain limits for corrugated panels

“…Kress and Winkler [23] derived the analytical expressions of the equivalent orthotropic plate when the corrugations are defined as circular arcs. A planar finite element was developed [24], and the transverse shear response was also taken into account by Filipovic and Kress [25,26]. Dayyani et al [27] investigated the tensile and flexural properties of corrugated laminate panels using numerical and experimental methods.…”
