“…In this study, a penalty-parameter material model (PPMM) was employed to account for the wrinkling, and the induced anisotropy due to the creases was considered. In addition, Gough et al [19] performed a series of experiments to measure the nonlinear properties of the creased membrane. However, it was done for relatively high stress range.…”

“…However, the residual stress during creasing was not considered. Gough et al [19] used the membrane elements for the analysis of a corner-loaded square membrane with transverse crease lines. In this study, a penalty-parameter material model (PPMM) was employed to account for the wrinkling, and the induced anisotropy due to the creases was considered.…”

Wrinkling analysis of a rectangular membrane with a single crease under shearing is performed to understand the wrinkle-crease interaction behaviors. The crease is considered by introducing the residual stresses from creasing and the effective modulus into the baseline configuration with assumed circular cross-sectional crease geometry. The wrinkling analysis of the creased membrane is then performed by using the direct perturb-force (DP) simulation technique which is based on our modified displacement components (MDC) method. Results reveal that the crease may influence the stress transfer path in the membrane and further change the wrinkling direction. The crease appears to improve the bending stiffness of the membrane which has an effective resistance on the wrinkling evolution. The effects of the crease orientation on wrinkle-crease interaction are studied toward the end of this paper. The results show that the wrinkling amplitude, wavelength, and direction increase as the crease orientation increases, and the wrinkling number decreases with the increasing crease orientation.

This paper presents a study of a square membrane, creased according to the Miura-ori folding pattern. When the membrane is allowed to expand from its packaged configuration, it initially expands elastically under zero corner forces. Starting from this naturally expanded configuration, the paper investigates the stress distribution and the load-displacement relationship when in-plane, diagonal loads are applied at the corners. It is found that out-of-plane bending is the main load-carrying mode and, for stress magnitudes typical of current solar-sail designs, the behavior of the membrane remains linear elastic. A simple analytical model, originally proposed for randomly creased membranes, is shown to predict with good accuracy the load-displacement relationship of the corners. It uses physically based and hence directly measurable membrane parameters.

“…Furuya et al (4) formulated the deployment characteristics of a one-dimensional creased membrane, where the curved beam theory was employed to calculate the rotational stiffness of the crease. Gough et al (5) introduced nonlinear anisotropic finite elements on the creased area to investigate the wrinkling behavior of a creased membrane using FEM. Papa et al (6) represented the crease as the initial configuration observed in the experiments to examine the stress distribution and the load-displacement rela-tionships of the Miura-ori folding pattern.…”

This paper addresses a elasto-plastic behavior of creasing process for a z-fold membrane to examine the mechanical properties of the crease, which determine the folding and deployment characteristics of a large membrane. To examine the elasto-plastic behavior in terms of the layer pitch and the contact force for creasing the membrane, fold experiments are performed. The experimental results are evaluated numerically by demonstrating elasto-plastic FEM analyses, and examined theoretically by introducing a mathematical model. In the FEM analyses, the precision is improved by investigating numerical parameters; the penalty stiffness for the contact analyses, the numerical damping in the equilibrium equation, and the size of the finite element mesh, which are dominant parameters in non-linear FEM analyses. In the mathematical model, the mechanics of the creasing process is formulated for elastic deformation. These results indicate that the loading process of the creasing properties is confirmed in terms of the contact force and the layer pitch. On the other hand, the further examinations are requested for the unloading behavior to determine the mechanical properties of the crease precisely.
