Advanced Engineering Materials, EarlyView.This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Advanced Engineering Materials, EarlyView.The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.

Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Effect of Stress on Field Dependence
Perceptual and Motor Skills, 197660 subjects were tested in the rod-and-frame test under flicker conditions (stress). As compared to scores in a control situation (no flicker), the rod-and-frame scores were large under stress and increased monotonically during the session. Furthermore, both intra- and interindividual variability of rod-and-frame performance changed under stress ...

Field-induced stresses in field emitters
Surface Science, 1978Abstract A numerical analysis is performed in order to determine the magnitude and disposition of field-induced stresses in an axisymmetric field emitter whose profile is taken as a calculated profile of a real tungsten emitter. The results are compared to previous analyses and new observations are made. Conclusions are drawn which reflect the effect

Abiotic stress, the field environment and stress combination
Trends in Plant Science, 2006Farmers and breeders have long known that often it is the simultaneous occurrence of several abiotic stresses, rather than a particular stress condition, that is most lethal to crops. Surprisingly, the co-occurrence of different stresses is rarely addressed by molecular biologists that study plant acclimation.

Stress Fields in Composite Laminates
International Journal of Solids and Structures, 1978A new theory is proposed to define the complete stress field within an arbitrary composite laminate. The theory is based upon an extension of Reissner’s variational principle to laminated bodies. Weaknesses in previous laminate theories are discussed and it is demonstrated how these are overcome in the present formulation.

Confusion and Controversy in the Stress Field
Journal of Human Stress, 1975An attempt is made to further clarify present areas of controversy in the stress field, in response to a two-part article by Dr. John W. Mason which concludes in this issue of the Journal of Human Stress. The author tries to elucidate each source of confusion enumerated by Dr. Mason.

A Historical View of the Stress Field
Journal of Human Stress, 1975An analysis is presented of selected aspects of stress theory and research in biology and medicine, both before and after the introduction of Selye's stress formulations, which have been of major importance in the development and popularity of this research area.
