Use of split Hopkinson pressure bar for testing off-axis composites

Tensile strength of the brittle materials, probabilistic or deterministic approach?

“…Assuming nondispersive one-dimensional wave propagation theory, the applied velocity o f deformation corresponds to 275/s in this paper. The obtained stress amplitude due to this applied velocity o f deformation assures the dynamic equilibrium theoretical approach that the dynamic fracture time o f material must not be less than three times o f celerity in this material [17]. Figure 11 shows a typical dynamic fracture results and in Table 3, there are the measured mean maximum strength and standard deviation values.…”

Dynamic tensile stress–strain characteristics of carbon/epoxy laminated composites in through-thickness direction

“…Therefore, it is required to characterize the dynamic behavior of composite materials. To date, the in-plane compressive [1][2][3][4][5][6][7][8][9][10][11][12], tensile [13][14][15][16][17][18] and interlaminar shear [19][20][21][22][23][24] properties of composite materials under dynamic loading have been determined with the conventional [25] or modified split Hopkinson pressure bar (SHPB). Nevertheless, except for Refs.…”

Propagation of a stress wave through a virtual functionally graded foam

“…The SHPB technique has proved to be extremely versatile and has grown from its original configuration for compression testing to include tension, torsion and fracture testing [20]. It has been used to characterise the dynamic response of a multitude of materials such as soils [21], composites [22], compliant materials [23] and metals [24]. Foams have also been studied using the SHPB technique [25].…”
