Effects of ThermoMechanical Coupling in Tribological Surface Transformations: A One-Dimensional Modelling Including Irreversible Solid-Solid Phase Transformations and Classical Plasticity

Figure 1

(a) Numerical example of TSTs: bar subjected to a thermomechanical loading (where 𝐿=10mm). (b) Boundary conditions (where 𝑇₀=300K): the loading function 𝜎^𝑔₀(𝑡) (resp., 𝑇^𝑔₀(𝑡)) is represented in solid lines with 𝜎₀^𝑔(min)=−300MPa at time 𝑡_𝐷=10⁻¹s (resp., dashed lines with 𝑇₀^𝑔(max)=450K). Note that 𝑡_𝐴=7.3×10⁻²s with 𝜎^𝑔₀(𝑡_𝐴)=−220MPa and 𝑇^𝑔₀(𝑡_𝐴)=409.5K; 𝑡_𝐵=7.5×10⁻²s with 𝜎^𝑔₀(𝑡_𝐵)=−224MPa and 𝑇^𝑔₀(𝑡_𝐵)=412K; 𝑡_𝐶=9.4×10⁻²s  with 𝜎^𝑔₀(𝑡_𝐶)=−283MPa and 𝑇^𝑔₀(𝑡_𝐶)=441K.
