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 ...

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

Advanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

Advanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

Cardiovascular reactivity, stress, and physical activity [PDF]

Frontiers in Physiology, 2013
Psychological stress has been proposed as a major contributor to the progression of cardiovascular disease (CVD). Acute mental stress can activate the sympathetic-adrenal-medullary (SAM) axis, eliciting the release of catecholamines (NE and EPI) resulting in the elevation of heart rate (HR) and blood pressure (BP).

Interpersonal Stress and Physical Complaints

Journal of Personality Assessment, 1974
Summary The relationship between a measure of interpersonal stress and report of physical symptoms was investigated. The data were obtained on 85 undergraduate students using a structured diary for a period of one week. A positive relationship was found between the diary measure of interpersonal stress and an overall tendency to report physical ...

Physical stress

2020
In this chapter, we have covered some of the general challenges in the physical stress of electronic devices. The benefits of using particles beams to evaluate the reliability of devices are various, such as a realistic error rate and a realistic error model.

Physical stress and catecholamine release

Baillière's Clinical Endocrinology and Metabolism, 1987
In both health and disease, noradrenaline and adrenaline concentrations in plasma increase with intensity and duration of exercise (Figure 1). These changes are only to a minor extent due to decreased catecholamine clearance (Figure 2). The increase in sympathoadrenal activity during exercise is primarily elicited by feed-forward stimulation from motor

Stress Fractures Caused by Physical Exercise [PDF]

Acta Orthopaedica, 1978
A series of 142 stress fractures caused by sporting activities and physical exercise is presented. 121 fractures occurred in athletes and 21 in non-competitive sportsmen. Distance runners presented with 68 fractures, skiers 12, sprinters 10, orienteering runners 9, vaulters 3, and football-players 3 fractures. Athletes engaged in other events had fewer
