THE WATER MODE PECULIARITIES OF SEABUCKTHORN GREEN CUTTINGS

Rossiiskaia selskokhoziaistvennaia nauka, 2021
The study of water-holding capacity in sea buckthorn green cuttings, as well as their ability to restore water content, has been carried out to improve nursery technological methods. In order to establish possible variety specifics, the varieties that significantly differ not only in their ability to rhizogenesis, but also in a range of biological ...

On the selection of the mode cut-off number in component mode reduction

Engineering with Computers, 2008
Dynamic analysis of very large and complicated FE structures such as FE full-vehicle structures are mainly performed with synthesized, component mode-reduced sub-models with common interfaces. The theory of component mode reduction (CMR) is well known, but it is not a simple application in real-live analyses.

Virtual modes in AT-cut resonators

Proceedings of the 2002 IEEE International Frequency Control Symposium and PDA Exhibition (Cat. No.02CH37234), 2003
Although studied for more than 40 years, drive-level dependent modes apparently remain an unresolved problem in the design and manufacture of high-performance AT-cut quartz crystal resonators. Our intention is to give a clear presentation of this phenomenon and what is known about these modes.

Ductile Mode Cutting of Glass

2019
Recently, the industrial application of glass has increased enormously because of its excellent and unique mechanical, physical, chemical and optical properties. However, machining of glass is still a major problem for the manufacturing industry since it is very brittle and high hardness.

Diathermocoagulation in Cutting Mode and Large Flap Dissection

Plastic and Reconstructive Surgery, 2011
The aim of this study was to determine the overall complication rate associated with the use of diathermocoagulation in cutting mode for flap dissection.Because of the high rate of complications generally associated with abdominoplasty, a large flap, abdominoplasty, or abdominal dermolipectomy model was chosen.

Ductile Mode Cutting Mechanism

2019
In this chapter, ductile mode cutting mechanism of brittle material is analysed theoretically and systematically. The coexisting crack propagation and dislocation extension in the chip formation zone are examined based on an analysis of cutting geometry and forces in the cutting zone, both on Taylor’s dislocation hardening theory and strain gradient ...

Modelling of Ductile Mode Cutting

2019
Although the demand for industrial applications for brittle material growing rapidly, the manufacturing of brittle material for making precise components is very challenging due to its poor machinability and brittleness. In this chapter, theoretical analyses are given based on brittle material’s mechanical properties as the functions of temperature and

CAM systems and cutting modes

2020
Creating a control program for machining a part on a CNC machine is a time-consuming process. The availability of modern CAD / CAM systems greatly facilitates the design process, both the part design and the processing technology. The article discusses methods for modeling and analyzing the processing process in CAM systems when developing control ...

Selection of cutting modes for basalt plastics

Technology of Metals, 2022
The analysis of the prospects for the use of basalt plastics in various industries has been carried out. The types of cutting tools used for machining PCM based on basalt fiber were studied. The results of mechanical processing of samples of basalt plastics by an end mill made of high-speed steel R6AM5, using a machine with numerical control in various
