Consistent and reasonable characterization of the material behavior under the coupled
effects of strain, strain rate and temperature on the material flow stress is remarkably crucial …

In this paper, a systematic evaluation of six ductile fracture models is conducted to identify
the most suitable fracture criterion for metal cutting processes. Six fracture models are …

Surface microstructure alteration is a major concern in industry to implement hard turning for
bearing steels. The formation of white layer in hard turning can be attributed to two main …

Machining processes on heat-resistant superalloys—ie, turbine cases, rings, or shafts—are
challenging tasks. The high-added value of such parts makes cycle times be longer than …

Waspaloy is a heat-resistant alloy primarily used in aircraft turbine engines, as forged
turbine and compressor disk, which is difficult to machine at room temperature due to …

Due to chip-flow interference and coordination, the two types of chips formed in the
processes of double-edged cutting make a remarkable difference to cutting force …

Machining process simulations are commonly used by manufacturing industries to
accurately predict machining force, time, and the performance of engineering components …

Constitutive equations were recognized for AZ31B magnesium alloy at higher temperatures
and strain rates from conventional empirical models like the original Johnson–Cook (JC) …

Magnesium alloys are biocompatible materials that are not only used in biomedical implants
but also in many engineering load-bearing applications due to their high strength to density …

Mechanical properties of the metals and their alloys are influenced by the material grain size
at microscale. In the present study, the Johnson-Cook (JC) material model is modified to …
