We study the plane strain thermomeehanical deformations of a viscoplastie body containing a rigid non-heat-conducting ellipsoidal inclusion a t the center. Two different problems, one in which the major axis of the inclusion is parallel to the axis of compression and the other in which it is perpendicular to the loading axis are considered. In each case the deformations are presumed to be symme...

We present a Data-Driven framework for multiscale mechanical analysis of materials. The proposed relies on the formulation in mechanics (Kirchdoerfer and Ortiz 2016), with material data being directly extracted from lower-scale computations. Particular emphasis is placed two key elements: parametrization history, optimal sampling state space. demonstrate an application prediction behavior sand,...

The deformation mode during hot rolling of plates and strips is very similar to ideal plane strain conditions. For this reason it is highly desirable to obtain this deformation mode during laboratory experiments. That’s why the PSC testing is now generally accepted as one of the most reliable methods for the generation of flow stress data and microstructural investigation of flat rolling. Inter...

With outstanding high-temperature properties, the intermetallic Mo5SiB2 alloy is regarded as an extremely competitive ultra-temperature structural material. The maximum Young’s modulus of 398.0 GPa for single crystals was found to be at vertex [010] direction, while minimum value 264.0 in [001] direction. For hardness, 451.7 HV after compression 1200 °C radial hardness 437.2 1300 axial directio...

The eccentric compression behavior of laminated bamboo lumber (LBL) columns with a chamfered section was investigated using eccentricity 30 mm, 60 90 mm and 120 mm. effect ratio on the ultimate bearing capacity, strain failure mode analyzed through tests. modes LBL different eccentricities were basically same, which belonged to brittle tension failure. With increase in ratio, capacity gradually...

Abstract. In the Laser Powder Bed Fusion (LPBF) process for metal components, a CAD file is sliced into layers with thickness of 20-80 micrometers and component built up layer by layer. For this purpose, powder applied in each case melted locally. This repeated until geometry completely established. The mechanical properties manufactured part are controlled cooling rate. It currently not consid...

Abstract The grain refinement technology is important in improving the metallic material properties without requirement of additional alloy elements. Previously, we developed an efficient method for producing ultrafine-grained steel strips using a combination cutting and heat treatment. However, effect on recrystallization was not apparent. objective this study to investigate effects metal stat...
