Phenol Neurolysis in Pain and Palliative Medicine. [PDF]

open access: yesPain Pract
ABSTRACT Background Pain is a common symptom in palliative care and affects patients' quality of life considerably. Standard analgesics are sometimes insufficient and are associated with substantial side effects. Neurolysis, the targeted destruction of nerves using thermal or chemical agents, offers an additional option for managing localized pain in ...

Dynamic failure characteristics of primary coal-rock combination under hydrostatic pressure

open access: yesMeitan xuebao, 2023
The surrounding rock of deep roadway is weak and the fissures are developed. Under the influence of mining disturbance, it is easy to cause dynamic disasters and the overall instability failure of coal rock combination is one of key factors inducing ...

Experimental study on dynamic mechanical behavior of frozen sandstone with different saturations

open access: yesMeitan kexue jishu, 2023
Water content is one of the critical factors affecting frost damage to rock masses in alpine regions. A dynamic disturbance load further complicates the issue.

Experimental study on energy dissipation and failure characteristics of rock at depth under non-hydrostatic pressure condition

open access: yesMeitan kexue jishu, 2023
Deep buried rock is often in a non-hydrostatic initial ground stress field, and the different stress states lead to different rock response under dynamic loading.

Energy dissipation and crushing characteristics of coal-rock-like combined body under impact loading

open access: yesYantu gongcheng xuebao, 2020
The impact compression tests on a single coal-like body, a rock-like body and a combined coal-rock-like body are carried out by using the split Hopkinson pressure bar (SHPB).

Towards Standardising SHPB Testing - A Round Robin Exercise [PDF]

open access: yesEPJ Web of Conferences, 2018
The Split Hopkinson Pressure Bar (SHPB) test, while widely utilised for high strain rate tests, has yet to be standardised. As an exploratory step towards developing a standard test method or protocol, a Round Robin test series has been conducted between four institutions: (i) Swinburne University of Technology, Australia (ii) University of São Paulo ...

Pulse shaping with soft material for SHPB [PDF]

open access: yesSCIENTIA SINICA Technologica, 2016
In the split Hopkinson pressure bar (SHPB) experiment, the state of dynamic stress equilibrium should be achieved over most of the test duration. Therefore, pulse shaping techniques which can modify the profile of the incident pulse are usually needed. In this paper, a new method for SHPB incident pulse shaping is presented.

Experimental study on impact dynamics and failure characteristics of coal specimen under true triaxial conditions

open access: yesMeitan xuebao, 2023
Deep coal is mostly in a three-dimensional unequal stress state. In order to study the dynamic characteristics of coal under impact load, the dynamic failure mechanics experiment of coal was carried out by true triaxial Hopkinson experimental system ...
