Chip Formation Mechanisms When Cutting Amorphous Alloy with Cubic Boron Nitride Tools Based on Constitutive Equation Parameter Optimisation [PDF]
MicromachinesOwing to potential inaccuracies in the current stress–strain curve used for constructing the Johnson–Cook (JC) constitutive model of amorphous alloys, the parameters of the JC constitutive equation were derived using Oxley’s cutting theory, negative ...

Comment on Cimmelli, V.A. Interpretation of Second Law of Thermodynamics in Extended Procedures for the Exploitation of the Entropy Inequality: Korteweg Fluids and Strain-Gradient Elasticity as Examples. Entropy 2024, 26, 293 [PDF]
EntropyIn a recent paper (Entropy 2024, 26, 293), Cimmelli makes use of the constitutive equation of Korteweg fluids to justify the introduction of an extended method to the classical Coleman–Noll procedure.

ACEOS – The additive and constitutive equation of state in the n-alkane homologous series
Chemical Thermodynamics and Thermal Analysis, 2022 The critical volumeVc, the relation between the critical temperature and the pressure Tc / Pc and the product PcVc2 depend linearly on the number of carbons in a homologous series as a consequence of the theory of corresponding states. This suggests that
