THE GROWTH OF THE VOID IN A HYPERELASTIC RECTANGULAR PLATE UNDER A UNIAXIAL EXTENSION

In the present paper, the finite deformation and stress analysis for a hyperelastic rectangular plate with a center void under a uniaxial ex tension is studied. In order to consider the effect of the existence o f the void on the deformation and stress of the plate, the problem is reduced to the deformation and stress analysis for a hyperelastic annu lar plate and its approximate solution is obtained from the minimum po tential energy principle. The growth of the cavitation is also numeric ally computed and analysed.
