Abbreviation for Finite Element Method, sometimes referred to as Finite Element Analysis or FEA.

Most well known FEM applications are COSMOS and FEMAP.

Still the best remains ANSYS.

Also MATHLAB developed a module for FEA which also uses programing capabilities of MATHLAB for optimization and different loading cases on the same analysis.

Material properties

  • Aluminium
    • Density (near r.t.) 2700 Kg/cm^3
    • Young's modulus 70 GPa
    • Shear modulus 26 GPa
    • Poisson ratio 0.35

Conform Lloyd's The basic grade of aluminium alloy is taken as marine grade 5083-0 with the following mechanical properties: N/mm2

    • 0,2 per cent proof stress (minimum) 125
    • Tensile strength 260
    • Modulus of elasticity 69 x 10^3

Delivery

  • indicate force - position and magnitude
  • indicate the proof stress, not the yield strenght
  • indicate the displacement
