Superplastic structural ceramics (Y‐TZP, Al 2 O 3 , Si N 4 and their composites) that can withstand biaxial stretching to large strains have been developed recently. Microstructural design of these first requires an ultrafine grain size is stable against coarsening during sintering deformation. A low temperature a necessary, but not sufficient, condition for achieving the required microstructure. In many cases, selection appropriate phase, such as tetragonal phase in zirconia or α silicon...
Existing and emerging methods in computational mechanics are rarely validated against problems with an unknown outcome. For this reason, Sandia National Laboratories, partnership US Science Foundation Naval Surface Warfare Center Carderock Division, launched a challenge mid-summer, 2012. Researchers engineers were invited to predict crack initiation propagation simple but novel geometry fabricated from common off-the-shelf commercial engineering alloy. The goal of international Fracture...
Ductile failure of structural metals is relevant to a wide range engineering scenarios. Computational methods are employed anticipate the critical conditions failure, yet they sometimes provide inaccurate and misleading predictions. Challenge scenarios, such as one presented in current work, an opportunity assess blind, quantitative predictive ability simulation against previously unseen problem. Rather than evaluate predictions single approach, Sandia Fracture relies on numerous volunteer...
Well placement optimization is important in reservoir management, but it challenging to implement due the high-dimensional solution space and large number of simulations required. Surrogate models may assist alleviate computational burden by efficiently approximating full-order models. Although deep learning has been proven be effective for surrogate modeling, most surrogates are purely data-driven, underlying physical principles or theories subsurface flows not considered. In this work, a...
Flexible grippers with superior gripping capabilities are essential for carrying objects. Herein, an origami chomper‐based flexible gripper is designed using a combination of the technique and newly developed nonlinear topology optimization method. This novel exhibits performance, as revealed by series experiments, including range capability under identical input load, maximum ratio, adaptability, achieving richer characteristics size scaling. The can handle wide object irregularities in...
There are few studies on the health effects of long-term exposure to neighborhood greenness in a longitudinal setting, especially Asian countries with high population densities.
Through close control over green‐state powder processing, pure alumina ceramics of 0.5‐μm grain size were obtained by sintering at 1250°C. The static growth this material was modest temperatures below 1300°C. However, dynamic occurred rapidly during superplastic deformation. Therefore, although the ultrafine‐grained exhibited rather low initial flow stress relatively deformation temperatures, grain‐growth‐induced strain hardening gave rise to high causing cavitation and cracking. As a...
Simultaneous application of colloidal processing and liquid‐forming additives to alumina resulted in a sintered density >99% 1 h at temperature as low 1070°C for commercial high‐purity powder total dopant level 2 mol%. The were 0.9% CuO + TiO 0.1% B O 3 MgO. At higher temperatures or after prolonged sintering, the doped ceramic developed duplex microstructure containing large elongated grains exhibited relatively high fracture toughness ∼ 3.8 MPa · m 1/2 compared value 2.6 undoped alumina.
