Experimental study on equilibrium initiation and extension of multiple clusters of fractures based on true triaxial physical simulation

Journal of Natural Gas Geoscience, 2023
In the context of tight sandstone reservoirs in the Ordos Basin characterized by compact and heterogeneous rock formations, conventional fracturing techniques yield monolithic fracture shapes, rendering 3D reservoir reconstruction unattainable.

Experimental study on coupling effects of cyclic confining pressure and intermittent cyclic loading on deformation behavior of saturated soft clay

Yantu gongcheng xuebao
The deformation characteristics of soft clay under intermittent cyclic loading and cyclic confining pressure are studied by conducting two types of cyclic triaxial tests, i.e., continuous cyclic loading and intermittent cyclic loading triaxial tests, and

Experimental study on deformation behaviors of saturated soft clay under intermittent cyclic loading with various drained conditions

Yantu gongcheng xuebao
In the previous studies, the cyclic triaxial tests under intermittent cyclic loading are used to study the deformation characteristics of soft clay under traffic loads. Both confining pressure and deviator stress vary cyclically in the stress field under

Coupling effects of cyclic confining pressure and loading frequency on deformation behavior of saturated soft clay under intermittent cyclic loading

Yantu gongcheng xuebao
After the train passes away, the subgrade soils undergo cyclic loading and intermittent periods. The existence of the intermittent period can also affect the mechanical properties of soil.

Effects of intermittently applied cyclic loading on proteoglycan metabolism and swelling behaviour of articular cartilage explants

Osteoarthritis and Cartilage, 1999
The aim of this study was to evaluate the effect of tissue load, frequency and load duration on the biosynthesis and release of proteoglycans (PGs) as well as on the swelling behaviour of cultured mature bovine articular cartilage superimposed with intermittent loads.Cyclic compressive pressure was introduced for 1, 3 or 6 days using a sinusoidal ...

Preparation of Tin-doped Carbon Hollow Spheres and Their Electrocatalytic activity in Water Electrolysis

International Journal of Electrochemical Science, 2013
Hollow carbon sphere electrocatalysts were synthesized by combining the hydrothermal and intermittent microwave heating (IMH) technique. The addition of P123 as surfactant has created huge amount of pores, resulted in the ultrahigh surface area of 1300 ...

Influence of load interval on dynamic properties of subgrade fill in cold regions

Case Studies in Construction Materials
The real simulation of vehicle loads is the key to studying the dynamic behaviors of subgrade fill in cold regions. Considering the time interval between adjacent vehicles, a series of dynamic triaxial tests with continuous and intermittent cyclic ...

A Dynamic, Self-Tensioning Suture Contracts in Saline to Counteract Changes in Loop Length From Cyclic Loading

Arthroscopy, Sports Medicine, and Rehabilitation
Purpose: To compare the biomechanical performance of a suture with proposed dynamic self-tensioning properties with that of commonly used high-tensile sutures by evaluating suture loop length changes, responses to cyclic loading, and failure testing with
