Analysis of geometrically nonlinear anisotropic membranes: theory and verification

“…That is, every material particle position is referred to the undeformed configuration. A material particle in the initial undeformed configuration is identified in a fixed global Cartesian coordinate system as X = X i e i (1) and its position in the deformed configuration at time t can be described as…”

“…Several examples are airbags in the automobile industry [1], parachutes and parafoils in airdrop applications [2], and pneumatic muscle actuators that are used in the robotics industry [3,4] and more recently for parachute control [5]. In many such applications, the membrane structure undergoes large rotations and displacements, but not necessarily large strains.…”
