The behavior of sand crushing will appear when the confining pressure is up to a certain value, which results in disappearing of the positive dilatancy of sand. Adopting a new hardening parameter with the crushing stress, an elastoplastic constitutive model considering sand crushing is proposed. Comparing the conventional triaxial compression test results with the model prediction, it shows tha...

Abstract This paper reports the main results of an experimental study on mechanics intensely fissured natural clays, extending our previous studies scaly clay from Santa Croce di Magliano. While work focused influence orientation fissures with respect to loading direction, present investigation specifically explores additional, important variable: stress level. The combined effect fissure and c...

In this paper, we explore the self-pinched transport of heavy ions in an inertial confinement fusion reactor chamber environment. The bulk of this work is carried out using a hybrid particle-in-cell code. The initial results show that a neutral flibe pressure of roughly 5–50 mtorr is sufficient to produce a net current capable of confining the ions at small radius (<5 mm). The source and sensit...

We discuss the baryon properties under a strong magnetic field. adopt Skyrme model and calculate field dependence of mass pressure distribution in soliton. elucidate magnetically induced contribution to sum rule interpret it as an extra confining force. also quantize soliton estimate difference between proton neutron find simple relation differences.

To provide technical support for gas extraction and accident prevention technology, the permeability law of in coal seams under different ground stress pressure has been explored. The evolution sample confining was deeply studied by using rock mechanics–permeability test system TAWD-2000. conclusions are as follows. samples can be divided into three stages whole stress–strain process, gradually...
