This work presents a numerical investigation of plasto-elastohydrodynamic lubrication for textured rough surfaces. The work is novel, the results are interesting, and the manuscript is well-written. Some minor revisions are needed though before this work can be published, as detailed below:

1- Acronyms should be fully expanded at first occurrence in the text. For example, Greenwood and Tripp for GT, Greenwood and Williamson for GW, Kogut and Etsion for KE, etc.

2- Section 2: It should be made clear to the reader that steady-state operation is assumed by considering that the rough surface is not moving, and that only the smooth one is. This allows for the use of the steady-state averaged Reynolds equation, provided in section 2.2. In addition, the underlying assumptions behind the numerical model should be clearly stated. For example, it is not clear whether or not the lubricant is assumed to be isoviscous and incompressible. If so, this should be stated. Otherwise, pressure-dependence relations for density and viscosity should be provided.

3- I believe “composed elastic modulus” should be “composite elastic modulus” throughout the text.

4- Page 8, line 57: I believe “Eqs. (10)” should be “Eq. (13)”.

5- Page 9, lines 3-5: aren’t the values of k and s problem specific? Or are these values universal, irrespective of the choice of materials and surface characteristics. Some clarifications are needed as to the choice of the values of these parameters. Referring the reader to [32] is not sufficient.

6- Figure 3: I believe the “Yes” and “No” for the “h_w(x,y)

The authors have carefully revised their manuscript to address all of my comments. It is now acceptable for publication in its current form.
