Creep Characteristics and Creep Model of Coal Based on Pore Water Pressure

Processes, 2023
Anthracite in a specific area of Shanxi Province is the subject of this essay’s research. In the creep studies, different porosity intervals and pore water pressures were employed to evaluate the mechanical properties of creep under various test paths.

A memory-dependent three-dimensional creep model for concrete

Case Studies in Construction Materials
The study of creep models for concrete is of great significance in analyzing and predicting the long-term stability of concrete structures. Based on the theory of memory-dependent derivatives, memory-dependent viscous dashpots that can describe the ...

Creep via dynamical functional renormalization group

, 1998
We study a D-dimensional interface driven in a disordered medium. We derive finite temperature and velocity functional renormalization group (FRG) equations, valid in a 4-D expansion.

Creep-Fatigue Life Evaluation of Solder Based on Creep Characteristics.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1998
Torsional fatigue tests and creep tests were carried out on a 60Sn-40Pb solder. In both tests three temperatures (303∼333K) were used, and in the fatigue test five cycling frequencies (0.001∼5.0 Hz) were used. An evaluation method for the solder fatigue life under relatively high temperature or low cycling frequency was proposed from the test results ...

Current-driven vortex dynamics in untwinned superconducting single crystals [PDF]

, 1997
Current-driven vortex dynamics of type-II superconductors in the weak-pinning limit is investigated by quantitatively studying the current-dependent vortex dissipation of an untwinned YBa2Cu3O7 single crystal.

NRASQ61R Expression in Lymphatic Endothelial Cells Causes Enlarged Vessels, Hemorrhagic Chylous Effusions, and High Mortality in a Mouse Model of Kaposiform Lymphangiomatosis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.
