To solve the problem of springback in traditional multi-point forming (MPF), a new process, namely, with individually controlled force–displacement (MPF-ICFD), is proposed. In this manuscript, MPF and MPF-ICFD are compared. Taking cylindrical surface as research object, change plate analysed by experiments, distribution strain wall thickness numerical simulation. Theoretical analysis used to ca...

This paper investigates different approximation techniques for planar beam column elements in force-basedmethods. The three fields, introduced in this review, are: curvature-based displacement interpolation CBDI used in matrix-based flexibility formulations, linear displacement approximation applied in state space, and higher-order displacement approximation utilized again in state space. Using...

2014 Geometrical aspects of Kossel diagrams obtained in light diffraction experiments are considered. Using a computer, orthogonal projections of spherical Kossel diagrams are drawn for b.c.c. and f.c.c. crystals of different densities. Theoretical diagrams are compared with the experimental results.

The distribution of hemodynamic shear stress throughout the arterial tree is transduced by the endothelium into local cellular responses that regulate vasoactivity, vessel wall remodeling, and atherogenesis. Although the exact mechanisms of mechanotransduction remain unknown, the endothelial cytoskeleton has been implicated in transmitting extracellular force to cytoplasmic sites of signal gene...

We have calculated the thermal noise of a v-shaped AFM cantilever (Microlever, Type E, Thermomicroscopes) by means of a finite element analysis. The modal shapes of the first 10 eigenmodes are displayed as well as the numerical constants, which are needed for the calibration using the thermal noise method. In the first eigenmode, values for the thermomechanical noise of the z-displacement at 22...

The discrepancy between the plow width and tractor leads to asymmetry of plowing units. geometry plowshare surface moldboard contributes generation lateral forces on working tool. All this imbalance tool deviation from straight-line movement during plowing. To maintain movement, driver has adjust machine every 5-10 meters, which is highly tiresome. study causes slips unit, we constructed a math...

Seawalls are built for Protecting of beaches against waves and preventing the progression of water to the beach. For a proper understanding about these constructions, a suiTable information about applied loads on these constructions should be existed. One of the important load that applied on these constructions is sea wave. Others loads are included: weight force of the walls, weight force of ...

The present study focusses on the damping force control of shear mode magnetorheological (MR) damper for seismic mitigations. Therefore, the semi-active MR damper which can control the vibration is analyzed both experimentally and numerically. Carbonyl iron is used as the magnetic particle and Castrol Magnetec oil as carrier fluid throughout the study. MR damper is designed and fabricated, and ...

Because primate studies provide data for the current experimental models of the human oculomotor system, we investigated the relationship of lateral rectus muscle motoneuron firing to muscle unit contractile characteristics in the squirrel monkey. Also examined was the correlation of whole-muscle contractile force with the degree of evoked eye displacement. A force transducer was used to record...

The purpose of this study was to investigate the initial displacement of the upper dentition and the nasomaxillary complex as a result of different directions of force application, and to determine the initial centres of resistance for both the upper dentition and the nasomaxillary complex. A macerated human skull with a well-aligned upper arch was used as one experimental model and Araldit 208...
