Abstract Development of three-dimensional continuum models for paperboard is an active field and the need reliable measurements to calibrate validate such evident. An experimental device protocol cyclic out-of-plane loading developed. This sequence present during converting operations paperboard. The tests reveals that commonly observed soft initial non-linear response compression a structural ...

The paper concerns the mechanical performance of continuous fibre/thermosetting polymer matrix composites reinforced in the through-thickness direction with fibrous or metallic rods or threads in order to mitigate against low delamination resistance. Specific illustrations of the effects of microfasteners in reducing delamination crack growth are made for Z-pinned and tufted composites. Respons...

The large deflection phenomenon of an initially flat circular membrane under out-of-plane gas pressure loading is usually involved in many technical applications, such as the blister or bulge tests, where a uniform in-plane stress often present before deflection. However, there still lack effective closed-form solution for problem with initial stress. In this study, formulated and solved analyt...

The dynamic propagation of a bifurcated crack under arbitrary loading is studied. Under plane loading con2gurations, it is shown that the model problem of the determination of the dynamic stress intensity factors after branching is similar to the anti-plane crack branching problem. By analogy with the exact results of the mode III case, the energy release rate immediately after branching under ...

In this paper, the new version of differential quadrature method (DQM), for calculation of the buckling coefficient of rectangular plates is considered. At first the differential equations governing plates have been calculated. Later based on the new version of differential quadrature method, the existing derivatives in equation are converted to the amounts of function in the grid points inside...
