A mathematical model of the process of rolling flux-cored tapes

Designing a kinematic module with rounding to model the processes of combined radial-longitudinal extrusion involving a tool whose configuration is complex

“…The value of the reduced pressure deformation of the kinematic module Z3r, taking into consideration (3) to (6), is expressed by a ratio or is calculated from the following formula:…”

“…In this context, the priorities are determined by the search, development, and implementation of state-of-the-art science-intensive technologies, as opposed to the classic techniques of part shape formation by removing chips. In modern realities, the variety of methods for processing metals by pressure (PMP) renders relevance to the task of choosing the most rational and economically one defined in [1][2][3][4][5][6][7][8][9]. Examples of successful solutions of specific practical issues [2][3][4][5] are inextricably linked with the development and constant improvement of finite-element modeling methods, statistical data processing [4][5][6].…”

That makes it possible to expand the boundaries of applying the selected deformation technique by determining the optimal manufacturing modes, tool configuration, as well as the conditions that provide for the quality of resulting articles [3,7].…”

“…That makes it possible to expand the boundaries of applying the selected deformation technique by determining the optimal manufacturing modes, tool configuration, as well as the conditions that provide for the quality of resulting articles [3,7]. Theoretical advancements in the research of a wide range of processes relate to the development and improvement of methods for describing the shape of bodies, searching for criteria and procedures for simplifying the assessment of force regimes, and the shape formation of semi-finished articles [2,6,7].…”

Study into the rolling of a double-layered powdered core in a metallic sheath

“…The effect of friction, feed force on the distribution of material porosity over the cross-section of a workpiece was established. Paper [6] built a mathematical model of the rolling process of a powdered material in a sheath, based on the numerical recurrent solution to a finite-difference form of the condition for static equilibrium in the selected elementary volume of a metal. The special feature of a given model is taking into consideration the plastic deformation of a metal sheath at a deformation site.…”
