“…A modified Johnson-Cook model was proposed by Lin [15] to overcome these drawbacks, and has been successfully applied to predict the flow stress in 20CrMo [8], titanium matrix composites (TiCp/Ti) [16], and Co-27Cr-5Mo alloy [17], etc. An Arrhenius-type model was applied to hot working by Sellars and Tegart.…”

Abstract:Isothermal uniaxial compressions of a Ti-6Al-4V alloy were carried out in the temperature range of 800-1050 • C and strain rate range of 0.001-1 s −1 . The effects of friction between the specimen and anvils as well as the increase in temperature caused by the high strain rate deformation were considered, and flow curves were corrected as a result. Constitutive models were discussed based on the corrected flow curves. The correlation coefficient and average absolute relative error for the strain compensated Arrhenius-type constitutive model are 0.986 and 9.168%, respectively, while the values for a modified Johnson-Cook constitutive model are 0.924 and 22.673%, respectively. Therefore, the strain compensated Arrhenius-type constitutive model has a better prediction capability than a modified Johnson-Cook constitutive model.

“…This is because the original JC model assumes that thermal softening, strain rate hardening and strain hardening are three independent phenomena and can be isolated from each other. Many modified JC model have been proposed with considering the couple effects of temperature and strain rates [13][14][15] . Therefore, in this section, a modified JC model will be proposed to describe the flow stress of CP-Ti under different deformation conditions.…”

Synthesis, Crystal Structure, and Optical Property of the Quaternary Semiconductor La 4Cd4In2S13. -The title compound is prepared by solid state reaction of a stoichiometric mixture of the elements (evacuated silica tube, 850 C, 4 d). The new quaternary sulfide is characterized by XRD and UV/VIS/NIR diffuse reflectance spectroscopy. La4Cd4In2S13 crystallizes in the orthorhombic space group Pbam with Z = 4. The structure consists of double chains of CdS 6 octahedra that are connected by single chains of InS 6 octahedra by edge-sharing into one-dimensional ribbons. These ribbons are further fused by infinite one-dimensional chains of InS4 tetrahedra by corner--sharing into Z-shaped [Cd 4In2S13] 12-layers which are separated by La 3+ ions. The compound exhibits an optical band gap of around 2.27 eV.

“…However, the coupled effects of; strain rate, temperature and strain on the flow stress of cobalt chromium should be considered in order to provide an accurate prediction of deformation behaviour [18]. To account for these coupled effects many authors have modified the original JC equation for a variety of materials [18][19][20][21][22][23]. Among them, Song et al [19] modified the original JC model by coupling the effects of temperature and strain rate.…”

Cobalt Chrome is used extensively within the biomedical industry for hip, knee and shoulder prostheses. These components are manufactured using a range of different processes which includes machining. In order to develop Finite Element Models of machining processes, it is necessary to develop the constitutive model of the workpiece material at high strain rates over different temperatures. During this research, Split Hopkinson Pressure Bar tests were conducted over a wide processing domain of temperatures (298-873 K) and strain-rates (600-1400s-1) to predict the constitutive model of biomedical grade Cobalt Chrome based on modified Zerilli-Armstrong, modified Johnson-Cook and strain compensated Arrhenius-type models. The prediction capability of these models was evaluated in terms of average absolute relative error and correlation coefficient between predicted and experimental flow stress values. Results demonstrated that the modified Zerilli-Armstrong model can track the deformational behaviour more accurately throughout the entire processing domain investigated compared to the other models. The model recorded an average absolute relative error of 2.71% and a correlational coefficient of 0.98.
