Transformation mechanism of microstructure and residual stress within hardening layer in PSHG
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2015 The Pre-stressed Hardening Grinding (PSHG) is presented combining with the advantages of Pre-stressed Grinding and Grinding Hardening. In order to study the variation mechanism of metallographic structure and the residual stress within hardening layer ...

On Pre-Stressed Hull Structures
International Journal of Recent Development in Engineering and Technology, 2021 “Wave-piercing” super-planing trimaran with air-born unloading, WPT, is developing of “wave-piercing” catamaran, WPC, for twice bigger achievable speeds. As all fast vessels, WPT needs for minimal weight of hull structures. Using of pre-stressed structures is a novel method of hull weight decreasing.

Principal component analysis of salivary cytokines and hormones in the acute stress response
Frontiers in Psychiatry, 2022 The acute stress response is characterized by activation of multiple interconnected systems in the body, resulting in the release of a flood of hormones and immune mediators into circulation.

THE ESTIMATION OF PRE-STRESS FROM AE CHARACTERISTICS IN CYCLIC LOADING OF THE PRE-STRESSED ROCK
Doboku Gakkai Ronbunshu, 1992 先行応力を人為的に与えた岩石の繰り返し載荷試験時に計測されたAEの発生特性から先行応力の推定を行い, 先行応力推定に及ぼす経過時間の影響について検討した. その結果, 先行応力除荷後の経過時間が長くなるとカイザー効果が不明瞭になるが, その場合においても, 2回目以降の載荷時において先行応力相当点にAE急増点が出現し, 先行応力を精度良く推定できることを示した. この繰り返し載荷時のAE特性による推定精度は, 経過時間が400日までの範囲で平均1.5%であった.

Comparison of the effect of preload and curvature of composite laminate under impact loading [PDF]
FME Transactions, 2016 In this paper, the effect of preload on impact response of composite laminates is considered. To this aim, three specimens were manufactured and tested under 4 different impact conditions: 1- A curved laminate without preload.

Neuroendocrine and immune pathways from pre- and perinatal stress to substance abuse
Neurobiology of Stress, 2018 Early life adversity is a documented risk factor for substance abuse and addiction. The pre- and perinatal period (i.e., from implantation, through pregnancy, to 6 months of age) is a critical period marked by high biological plasticity and vulnerability,

, 2023 AbstractReinforcement of the pre-stressed concrete cylinder pipes with external pre-stressed strands is an effective way to enhance a prestressed concrete cylinder pipe’s ability to bear the design hydraulic pressure. A theoretical derivation is studied, and this formula derivation could be used to determine the cross-sectional area per unit length ...

INSTABILITY OF A PRE-STRESSED SOLID–FLUID MIXTURE [PDF]
Waves and Stability in Continuous Media, 2006 A solid-fluid mixture is generally modelled assuming that the state of stress in the reference configuration is identically equal to zero. However, such an assumption is not always appropriate to take into account some instability phenomena occuring in Nature.

Analysis of Stresses in Tapered Rectangular Utility Pole [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2018 Power transmission is generally carried out through electric cables supported by transmission pole (Utility pole) of various materials and cross sections. However, their utilization depends on climatic conditions and external loads acting on them.
