Experimental studies have identified an anomalous grain size dependence associated with the critical tensile pressure that a metal may sustain before catastrophic failure by cavitation processes. Here we derive first quantitative theory (and its closed-form solution) capable of explaining this phenomena. The agrees well experimental measurements and atomistic calculations over very wide range conditions. Utilizing theory, are able to map out three distinct regimes in which for (i) increases...
Abstract Thermal stress weathering is now recognized to be an active and significant geomorphological process on airless bodies. This study aims understand the key factors governing thermal stresses in rocks bodies through extensive numerical calculations analytic analyses. Microscopic (grain‐scale) are driven primarily by maximum diurnal temperature variation at said depth. Macroscopic (rock‐scale) more complex. For rock sizes larger than skin depth, macroscopic second (and higher) order...
Simulations show that extremely high-powered microwave pulses can cause potentially injurious intracranial stresses.
Novel engineering materials and structures are increasingly designed for use in severe environments involving extreme transient variations temperature loading rates, chemically reactive flows, other conditions. The Texas A&M University Hypervelocity Impact Laboratory (HVIL) enables unique ultrahigh-rate characterization, testing, modeling capabilities by tightly integrating expertise high-rate behavior, computational polymer chemistry, multi-physics multiscale numerical algorithm...
