Model development and application. (a) A spider web model exhibiting orb web geometry with eight radially extending threads responsible for structural support and a spiral thread involved primarily in prey retention is developed. This geometry is abundantly found in spiders of both Deinopoidea and Araneoidea super families (i). Constant-velocity force increments are applied to a radial thread segment (shown in red) to study web deformation behaviour for various capture silk material properties (ii). (b) Force–displacement data for a web pulled in the out-of-plane direction until failure. Numerals (i–iv) correspond to web deformation states as shown in (c).
