... DYNAMIC FRACTURE occurs under a rapidly applied load, such as that produced by impact or by explosive detonation. In contrast to quasi-static loading, dynamic conditions involve loading rates that are greater than those encountered in conventional tensile tests or fracture mechanics tests. Dynamic...

... the yield criterion for porous material must be determined from combined stress tests that simultaneously apply a hydrostatic stress and a shear, or deviatoric, stress. One instrument for this purpose is a triaxial compaction cell, illustrated in Fig. 17 ( Ref 5 ). Through various combinations of triaxial...

The most important lesson for designers today is that the wood (a natural composite) in the Mosquito was used only to carry in-plane loads. Metal fittings were used for all triaxially loaded components—the landing gear...
