My parents may have refused my sister and me the cable TV that was our greatest childhood desire, but once a week (twice, if someone had the flu) they would brave the video store's long evening lines to replenish our dependable stack of VHS tapes, each of which came sheathed in a brittle plastic case, ribbed for easy gripping.
Energy absorbed by DHEC laminates is of the same order than for pure carbon ones; however, the DHEC failure mode (referred to as "petaling") presents a lower spreading of splinters respect to the pure carbon fibres (brittle fracture) case.
In plasma nitriding systems without auxiliary heating, nitrogen incorporation depends on the plasma current density and, therefore, temperature, which can be significantly higher at the tool edges, forming an excessive deep and brittle diffusion case, reducing the service life of the duplex treated tool.
Chemical milling treatment is one of the final steps in manufacturing titanium alloy components that removes the brittle alpha-case layer formed during various thermal processes.
The reinforcing steel never exceeds 8 percent of the cross-sectional area to guard against catastrophic brittle failure in case of accidental overloading.
In such case, brittle fragmentation of the magmatic foam can occur, for example, when the elongation strain rate of the foam ascending in the conduit exceeds its viscous relaxation time (Papale 1999).
Problems arise when the macroscopic failure mode is identical (i.e. brittle) in both cases (e.g. in composite systems).
The performance of our approach is demonstrated on a numerically and physically challenging 3D dynamic brittle-fragmentation test case.
In all of the cases, brittle fibers containing adhesives or sealants release the chemicals where and when the matrix cracks, causing the fiber to crack and release chemicals.
The new approach is illustrated in the case of brittle materials.
