Phenol Neurolysis in Pain and Palliative Medicine. [PDF]

Pain 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 ...

NUMERICAL MODELLING OF WAVE SHAPES DURING SHPB MEASUREMENT

Acta Polytechnica CTU Proceedings, 2019
The paper aims at the numerical simulation of the wave propagation in compressive Split Hopkinson Pressure Bar (SHPB) experiment. The paper deals with principles of SHPB measurement, optimisation of a numerical model and techniques of pulse shaping.

A method of incident pulse shaping for SHPB [PDF]

WIT Transactions on The Built Environment, 2014
The split Hopkinson pressure bar (SHPB) testing method has been widely used to obtain dynamic compression properties of solid materials. In the experiment, the state of dynamic stress equilibrium and deforming at a nearly constant strain rate over most of the test duration should be achieved. Therefore, pulse shaping techniques are usually needed.

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

EPJ 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 ...

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

Meitan 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.

Pulse shaping with soft material for SHPB [PDF]

SCIENTIA 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.

Dynamic Covalent Networks of Molecular Clusters for Hard and Impact-Resistant Glass with Feasible Processability. [PDF]

Adv Sci (Weinh)
Molecular granular material glass is fabricated by crosslinking sub‐nm POSS clusters with dynamic borate ester bonding while the materials combine high transparency, modulus, and hardness with superior impact resistance and (re)processability, offering a promising strategy for creating robust yet highly processable organic glasses.
