In June 2011, the White House set out an audacious goal for materials science: Cut in half the time it takes to get a newly designed material from the lab to the marketplace. Even the program’s name—the Materials Genome Initiative (MGI), inspired by the massive Human Genome Project—was chosen to reflect that broad ambition.

Anisotropic Hardening of Initially Orthotropic Materials
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1979AbstractA hardening model for an orthotropic material is proposed. The corresponding anisotropic parameters are the components of a fourth order tensor function of the plastic strain, entering a quadratic equation for the yield surface. Assuming polynomial dependence on the plastic strain, the most general form of a polynomial fourth order orthotropic ...

Initial Damage of Composite Materials
2019In composite materials, damage occurs even without excessive loading, because of the discrepancy between material parameters of adhered materials. This damage (damage of nonconformity) is expressed as a violation of the continuity at the interface. A mathematical model of the interaction of inclusion particles and the composite matrix, based on taking ...

Laser-initiated ablation of materials
2015Laser micromachining is now a common method of surface modification and machining; utilizing a broad spectrum of wavelengths, wave forms, and pulse durations. The most accurate bulk geometric modification is achieved by the use of ablation via the application of short wavelengths to deliver large photons for absorption in minimal skin depth.

The Material and Initial Symptoms
1953This study is based upon a critically selected series of 117 patients with chromophobe adenomas admitted to the Neurological Institute of New York or the Medical Services of the Columbia-Presbyterian Medical Center, from 1929 to 1948. The histologic material was prepared and made available by the Department of Pathology, Division of Neuropathology ...
