As a result, material was removed from both the electrodes.
Experimental Material of the test specimens Over the years, many materials have been used as fillers in rubber compounds.
Extraneous materials originating from the manufacturing process and equipment are typically also found in carbon black Table 1 Chemical composition of the test specimens Composition phr Rubber RSS3 100 Zinc oxide 5 Stearic acid 2 N220 Carbon Black 70 and 80 Aromatic oil 6 6PPD*1 1 TBBS*2 1.2 TMTD*3 0.2 Sulfur 2.5 *1 N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine *2 N-Tert-Butyl-2-Benzothiazole Sulfenamide *3 Tetra Methyl Thiram Disulphide Fig. 1 The rubber was mixed with N220 carbon black for this study Material cutting designation In this study, The copper tungsten was used as an electrode material for cutting mixed rubber.
In the future works, we may plan to conduct similar machining experiments using other kind of rubber materials.

Damping of geo-materials in resonant column test is commonly evaluated with two alternative experimental methods; during a steady-state vibration (SSV) and during free-vibration decay (FVD).
In the second part, the materials and experimental techniques of the study are described briefly and the background of determining material damping in a resonant column test is also presented along with the analytical formulae.
Introduction Stiffness (G) and damping (Ds) are important properties in order to capture the complete dynamic behavior of geo-materials.
Equipment, Materials and Methods A crushed rock of hard sub-angular to angular particles was tested in the study.

Materials and Method The Synthesis and Modification of Activated Carbon and SBA-15 Materials.
It is indicated that the reaming on SBA-15 materials increased the CO2 adsorption capacity and amine modification of materials also had a beneficial effect.
Compared with modified activated carbon materials, the modified SBA-15 materials have certain advantages in stability.
The maximum mass change was only 0.02 mg, indicating that both modified activated carbon materials and mesoporous materials SBA-15 have excellent cycle stability.
Cyclic adsorption properties of various materials are basically the same.

This article establishes a molecular scale model of PBO microfibers, which can deeply understand the phenomenon and characteristics of damage to PBO fiber materials through molecular dynamics optimization.
It also theoretically predicts the structure and physical properties of such materials, reveals their failure mechanisms, and provides technical support for the research and development of military materials. 1.
The PBO small molecule chain model in Fig. 1 was established using the Material Studio 2019.
The fracture strength is about 33 GPa and the elongation is 14.5%, making it a typical "strong and tough" material.
