On Stress State Measurements of Rock Massifs with Underground Facilities Convertible into Defense Shelters

“…It is no accident, therefore, that a great deal of experience has been accumulated at present in creating instruments and methods for assessing the stress state of rocks in massifs. Achievements in this area were summarized in sufficient detail in [3,4] and there is no need to repeat them [10][11][12][13][14]. We restrict ourselves to providing examples of actual measurements of the stress state of rocks in the massif, indicating the inconsistency of the measured stress values with modern ideas about the causes of the formation of the stress field in the earth's crust, the direction of the main stresses and their magnitudes.…”

Solving Problems in Geomechanics: Comparison of the Fidesys Strength Analysis System and the Plaxis Software Package

“…Note however that FEM studies were stimulated by the fundamental results of analysis of convergence and stability of finitedifference schemes, projective methods, and generalized solutions. Especially for geomechanics and characteristics of rocks have used methods of compare of the field tests and mathematical simulations [3,4].…”

Laser-Ultrasonic Testing of the Structure and Properties of Concrete and Carbon Fiber-Reinforced Plastics

“…In this connection, the development of a new technique based on laser ultrasonic structuroscopy with a view to diagnosing the structure and properties of advanced structural materials used in civil engineering looks promising, especially for new methods of Numerical Modelling of structural damage [12,13]. Created in the USA, non-contact laser ultrasonic spectroscopy [14] is designed to study the structure of carbon-polymer composites; composite samples should be less than 7mm thick at that.…”
