Johnson〤ook (JC) high temperature strength material models have been widely used in Finite Element Analysis (FEA) to solve variety of hot rolling problems. In this paper, the temperature and strain rate related
steel bar is 8-50 mm, and the recommended diameter is 8, 12, 16, 20, 25, 32 and 40 mm.Ribbed bars mainly bear tensile stress in concrete. The ribbed steel bar can bear the action of external force better because of the effect of...
aproceed to the wizard 进行巫术师 [translate] aClause 2.4.3.3). The yield strength may be any one of the yield parameters assessed by the tensile test of the parent metal, in megapascals Rm =the value defined above, in megapascals C = a factor = 2.35 for carbon steel [translate] ...
Furthermore, as the tensile strength of materials can be estimated from hardness data, this test is a valuable alternative to destructive and time-consuming tensile testing, which is difficult to be performed on small-sized materials. Therefore, Brinell hardness testing using a hard steel ball as...
With the use of wire breaker compounds containing the silicon-treated carbon blacks, excellent adhesion can be obtained to the steel cord. Additionally, it is also possible to reduce heat buildup in this component of the tire.The contemplated benefits obtained with the compositions set forth in ...
For the steel plates, the Johnson-Cook material model was employed. For the composite plates both in-plane and out-of-plane failure criteria were employed. In particular, a contact tiebreak formulation with a mixed mode failure criteria was employed to simulate delamination failure. As for the ...
Johnson–Cook (JC) high‐temperature strength material models have been widely used in finite‐element analysis (FEA) to solve variety of hot rolling problems. Herein, the temperature‐ and strain rate‐related parameters of JC model are experimentally calibrated for eight different steel grades ...
Nanocrystalline grained steel samples presented very high strength with low ductility. Once, in the ultrafine range, as the ferritic grain size was increased, the strength was decreased and the ductility was improved. The porosity and carbon atoms within the structure were analyzed in order to ...
Design/methodology/approach - This research uses a new approach to model a tensile test of a high-carbon steel on the basis of discrete element method (DEM). In this research, the tensile test specimen was created by using a DEM packing theory. The particle-particle bond model was used to...
in situ tensile testThe deformation and fracture behaviors of low-carbon steel, medium-carbon steel, and high-carbon steel were studied on internal microstructure using the scanning electron microscopy in situ tensile test. The microstructure mechanism of their deformation and fracture behavior was ...
