Evaluation of rock mass deformability using empirical methods – A review
Underground Space, 2017 Evaluation of rock mass deformability is an important but very challenging task in the analysis and design of underground structures in rock. Although various empirical (correlation) methods have been developed for determining the deformation modulus of ...

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Two sharp inequalities for operators in a Hilbert space
Researches in Mathematics, 2022 In this paper we obtained generalisations of the L. V. Taikov’s and N. Ainulloev’s sharp inequalities, which estimate a norm of function's first-order derivative (L. V. Taikov) and a norm of function's second-order derivative (N.

Fabrication of Bamboo Fiber Paper with Shellac and Its Effect on Specific Elastic Modulus
Journal of the Society of Materials Science, Japan, 2011 Specific elastic modulus of bamboo fiber paper was evaluated when the shellac was added into the paper during the paper making process. For the fabrication of the paper, bamboo fibers were treated with the alkali solution after extraction. The bamboo paper was fabricated with a heat pressing technique using the wet bamboo fibers sheet obtained by the ...

Optimization of the Production of Rubber Compounds Using Mathematical Models
Advanced Engineering Materials, EarlyView.Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...
