Fiber-reinforced composite materials are being widely used in engineered structures. This report examines how the general form of the Weibull Criterion, including the evaluation of the parameters and the scaling of the parameter values, can be used for the prediction of component failure.

A one-dimensional Lagrangian calculation of the implosion of a hydrogen gas puff is presented. At maximum compression, 60% of the mass is located in a density spike .5 mm off the axis with a half width of 40 ..mu..m. The temperature on axis reaches 200 eV.

An S-1 optical streak camera with 10-ps (optical) temporal resolution simultaneously records reflected 1.06-..mu..m laser light and suprathermal (> 30 keV) x rays from laser fusion targets. To make these measurements, the camera x-ray sensitivity is increased 30-fold without significant loss of temporal resolution by increasing the effective slit width from the normal 50 ..mu..m to 1500 ..mu..m. The measurement system is described and sample data are presented.

The main results are in the following 3 areas: (1) static and dynamic properties of the hydrogen diffusion model; (2) exact asymptotic solutions of the model; (3) new physics of the lattice hydrogen. The progress made during this period has been particularly significant. The hydrogen diffusion model has brought to light a number of puzzling features of hydrogen metal systems. These advances have made it possible now to begin to study some of the long-range objectives put forth in the initial proposal.
