Here, we present a detailed protocol of a new approach for conducting elevated temperature reverse normal plate impact, and combined pressure-and-shear plate impact. The approach involves the use of a breech-end resistive coil heater to heat a sample held at the front-end of a heat-resistant sabot to the desired temperature.

Brittle fractures tend to occur suddenly and without much material inelasticity; think of a bone fracture, for example. These failures often occur in situations where there is little ability for the material to develop...

Boiling Point Elevation The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Source: Lani-Louzada, R., et al., Full-Circle Cauterization of Limbal Vascular Plexus for Surgically Induced Glaucoma in Rodents. J. Vis. Exp. (2022)This video demonstrates the induction and monitoring of elevated intraocular pressure (IOP) in a rat model. The process involves cauterizing the limbal blood vessels, resulting in vessel occlusion and elevated IOP. The rat is then allowed to recover, and IOP is regularly monitored in both the experimental and control eyes for comparison.
FAQs
The heated condition adds a thermal variable to the material’s response during shock loading. This allows researchers to characterize constitutive behavior and strength under combined thermal and mechanical conditions, rather than examining shock response only at ambient temperature. The resulting information is relevant to designs expected to operate in extreme environments.
The flyer plate provides the impact, while the target plate receives it and transmits the resulting shock wave through the material. Controlling the flyer velocity and the temperatures of the test components establishes the loading conditions. These controls help researchers relate measured stress, particle velocity, and deformation to material behavior.
Stress, particle velocity, and deformation provide complementary evidence of how the material responds to the shock event. Together, these measurements help researchers characterize constitutive behavior and strength, while deformation indicates the resulting mechanical change. Interpreting the measurements as a group supports development of material models for high-rate, heated conditions.
A typical test establishes the required temperature and sets the flyer plate to a controlled velocity before impact with the target plate. The collision generates a shock wave, after which diagnostics record stress, particle velocity, and deformation. Researchers then use those observations to characterize the material response under the specified thermal and mechanical loading.
Engineers would choose this approach when a design must be evaluated under both shock loading and temperatures above ambient. It is especially relevant to components exposed to extreme environments, where material strength and constitutive behavior must be understood during combined thermal and mechanical loading. The results can support performance assessment and predictive engineering models.
The method supports research on metals, ceramics, and advanced materials whose behavior may affect systems operating under severe conditions. Its applications include aerospace, defense, manufacturing, and energy systems. Measurements from the tests help researchers develop models that predict failure and performance, providing engineering context for material selection and design under extreme loading.
