Fatigue life prediction of a B/A1 composite

摘要: Abstract The fatigue behaviour of a unidirectional boron reinforced aluminium composite under transverse loading was modelled by technique involving the iteration damage accumulation and internal stress redistribution. Damage in matrix can be described applying evolution law modified to account for strain level. redistribution stresses during calculated using finite element stiffness incorporating variable. A two-scale approach microelement macroelement used relate global local material. Using this approach, lives two composites based on 6061 alloy with 0.25 0.5 volume fractions respectively were predicted properties fibre materials.
