This article presents two methods to determine pressing forces to the M1 copper plate. The first approach employs the upper-bound method, and the second method combines numerical simulation with a central composite design. The upper-bound method uses physical analysis to determine the deformation zone and establish the division of the rigid block model. The findings were identical to the slip-line solution method.

In the paper "Analysis the influence of particle size to the macroscopic behavior of Duplex Ferrite/Martensite steel with RVE method" ferrite–cementite steel sheets have been widely used in cold forming processing such as drawing, bending, and blanking. For the normal hot rolled steel sheets with ferrite and lamellar pearlite phases, the strength is usually too high and the hard lamellar pearlite will also cause cracking or tearing during cold deforming.

Ebook "Physics of asymmetric continuum: Extreme and fracture processes - Earthquake rotation and soliton waves" include relations not only for the displacement velocities but also for a spin motion and basic point deformations as well. We include here the axial point - formation and twist point deformation represented by the string-string and string-membrane motions. A twist vector is defined here as a vector p- pendicular to the string-string plane and representing its magnitude. It - comes an important counterpart to spin and a key to the presented theory.

Ebook "Theory of charge transport in carbon electronic materials" has been an issue of intensive interests and debates for over 50 years, not only because of the applications in printing electronics, but also because of the great challenges in understanding the electronic processes in complex systems. With the fast developments of both electronic structure theory and the computational technology, the dream of predicting the charge mobility is now gradually becoming a reality.

This paper presents the results of determining the coefficient of friction when cold plastic deformation by the method of cold ring upsetting with different lubricants. The ring upsetting process is performed with varying degrees of deformation with three lubricants used: industrial oil, cooking oil, and zinc sulfate powder. Based on the deformation and dimension change of the samples after the upsetting, the coefficient of friction was determined by correlation comparison with the friction calibration curve performed by Male and Cockcroft.

During the diaphragm forming process, a vacuum seal is applied between the upper and lower diaphragms to compact and hold the laminate. Therefore, a thorough characterization of the in-plane shear behavior of fabrics under diaphragm forming conditions must take into account the effect of vacuumsealing and compaction between the two diaphragms during bias extension.

Understanding the tectonic mechanism generated by the earthquakes and faults is possible only if the preseismic, coseismic and postseismic crustal deformation related to the earthquakes is determined properly. By the analysis of continuous GPS (CGPS) coordinate time series, it is possible to estimate the crustal deformation. Besides, accelerometer records at strong motion stations (SMSs) may support the CGPS-based estimates.

In this paper, a combination between the indentation and scratching process was developed to analyze the deformation mechanisms and mechanical properties of Cu50Zr50 metallic glasses (MGs) using molecular dynamics (MD) simulation. The deformation mechanisms and mechanical properties of Cu50Zr50 MGs are appraised through the surface morphology, pile-up height, hardness, machining forces, and resistance coefficient. The influences of different indenter radius are clearly investigated.
