For experimental testing, two separate loading conditions were considered. Under the first condition, upper arms were loaded at 40 deg and the lower arms were loaded at −20 deg. For condition 2, upper arms were loaded at 10 deg, while lower arms were loaded at −45 deg. All angles are relative to the horizontal axis, with the origin at the device center. A weight of 250 g was applied to each mesh arm at the prescribed angle via soft tissue clamps.
