Abstract: A method of measuring millisecond-scale blast and impact characterization in soft materials includes embedding one or more sensors in soft material, wherein the one or more sensors have mechanical properties approximately matching the soft material; applying a constant current to the one or more sensors; subjecting the soft material to a shock or impact event; measuring a response as a change in voltage; and converting the measured voltage to strain or pressure.

Abstract: A handheld quality inspection tool for projection welded components and method for utilizing the same is disclosed. The handheld quality inspection tool includes an elongated hollow tube, a spring support, a spring member, a plunger, and a handle. The elongated hollow tube defines a slot. The spring support is connected to an end portion of the elongated tube. The spring member is disposed within the elongated hollow tube and connected to the spring support. The plunger is disposed in the elongated hollow tube and connected to the spring member opposite the spring support. The handle is connected to the plunger and protrudes from the elongated hollow tube through the slot and is translatable along the slot to move the plunger and compress the spring member. Upon release of the handle, the compressed spring member propels the plunger to apply an impact force to a projection welded component.

Abstract: A destructive inspection method of a vitreous silica crucible for pulling a silicon single crystal evaluates a crack state of an inner surface of the vitreous silica crucible supported by a graphite susceptor when a load is instantaneously applied to at least one point on the inner surface via an automatic center punch while pushing the tip portion of the automatic center punch against the inner surface. The destructive inspection method can inspect the vitreous silica crucible under conditions as close to the actual conditions of use as possible.
