FEM-analysis provides an accurate view of stresses around structural connections, hubs, hinges etc. Appropriate design of local details is crucial to prevent failures based on high stresses or fatigue. Aquastructures has extensive experience with FEM analysis of both plastic- and steel components.
In the aquaculture industry there is a wide use of plastic components in flexible collars. Brackets made of plastic, connects the floating tubes to the handrail, as well as to the net, sinker tube and mooring. The strength of the plastic brackets is therefore crucial in order to keep the collars integrity in exposed locations and during operations.
Aquastructures provides FEM-analysis on several types of steel components such as hubs, mooring connections and hinged constructions, to detect weaknesses in the structure. Details in constructions, that are exposed to waves, can be subject to fatigue problems. Fatigue calculations can also be performed with input from global analyses.
