Development of a model for flexural rigidity of fishing net with a spring mass approach and its inverse identification by metaheuristic parametric optimization

Exploring the mechanics of fish escape attempts through mesh

“…In a spring mass approach, each mesh twine is split into several rigid bars to model its bending stiffness (Vincent et al, 2020). Spring forces are located at the resulting nodes connecting two adjacent bars.…”

“…Equation ( 4) and equation deriving from inequality (5) were introduced in the netting dynamics solver, detailed by Vincent et al (2020) to solve the mechanical balance between the mesh and the fish and to establish a relation between fish propulsion force and the success of escape through a mesh.…”

“…The bench test also served to apply an aging cycle to a novel mesh before a test so as to respect the protocol described by Vincent et al (2020).…”

Review on the performances and applications of mesh-fabrics

“…But most experiments could rely on complex instrumentation and dedicated models or software. Vincent et al proposed a new methodology to determine mechanical and dimensional characteristics of common netting materials, including flexural rigidity, rest angle, knot length, and enables 56,57,88,90,94 the simulation of large deformation of nettings constructions, even 3D flexural rigidity (Figure 5(e)). The method had been applied to previous experimental results to prove its reliability and practicability.…”
