Spider orb webs rely on radial threads to absorb prey kinetic energy.
The kinetic energy of flying insect prey is a formidable challenge for orb-weaving spiders. These spiders construct two-dimensional, round webs from a combination of stiff, strong radial silk and highly elastic, glue-coated capture spirals. Orb webs must first stop the flight of insect prey and then retain those insects long enough to be subdued by the spiders. Consequently, spider silks rank a...

متن کاملInvestigation of Nonlinear Behavior of Material on Seismic Performance of Roller Compacted Concrete Dam
In this research, the effect of nonlinear behavior of concrete on seismic performance of roller compacted concrete (RCC) is discussed. Nonlinear behavior of material shows the behavior close to reality due to use of all structural capacity and it is considered the most appropriate method for design. So in this paper, by using the appropriate definition of nonlinear behavior of RCC, the Ansys so...
متن کاملPhase-Field Modeling of Nonlinear Material Behavior
Materials that undergo internal transformations are usually described in solid mechanics by multi-well energy functions that account for both elastic and transformational behavior. In order to separate the two effects, physicists use instead phase-field-type theories where conventional linear elastic strain is quadratically coupled to an additional field that describes the evolution of the refe...
متن کاملHigh-performance spider webs: integrating biomechanics, ecology and behaviour.
Spider silks exhibit remarkable properties, surpassing most natural and synthetic materials in both strength and toughness. Orb-web spider dragline silk is the focus of intense research by material scientists attempting to mimic these naturally produced fibres. However, biomechanical research on spider silks is often removed from the context of web ecology and spider foraging behaviour. Similar...
