Effect of Plastic Anisotropy on the Collapse of a Hollow Disk under Thermal and Mechanical Loading
Round 1
Reviewer 1 Report
This manuscript describing the plastic collapse of a thin orthotropic hollow disk taking into account plastic anisotropy.
The theoretical considerations of the author are based on the previous cooperation with professor Alexandrov and constitute their extension.
The manuscript is methodical and the Result & Discussion section is well organized with proper justifications. The paper is well-written and organised. My opinion is that it deserves publication in Symmetry journal.
It is suggested to add the picture showing boundary conditions in cylindrical coordinate system and distribution of stress components. It would enhance the readability of the article for nonspecialist readers.
Discussion section: Are there any implications based on the results of this study? Please specify.
Line 204: It is not clear for me how η and η1 in Equation (43) were determined. Moreover, source of these equations (Alexandrova, Alexandrov, https://doi.org/10.1115/1.1751183) have to be cited here.

Reviewer 2 Report
This paper presents the solution of the plastic collapse of a thin orthotropic hollow disk inserted into a rigid container. The load of the uniform temperature field and the uniform pressure were investigated. Two plastic collapse mechanisms are described. One of plastic mechanisms propose that the entire disk becomes plastic at the initiation of plastic yielding. The other plastic mechanisms propose that the plastic localization occurs at the inner radius of the disk with no plastic region of finite size. The analytical solution of the isotropic and orthotropic material is presented and interpreted on figures. The presented methodology of the plastic collapse mechanisms is interesting for the designers.

Reviewer 3 Report
The author presented the plastic collapse of a thin orthotropic hollow disk under thermal and mechanical loading. The paper is well organized and clearly illustrated. Here are some comments:
In the introduction section, more information and references are suggested for the background information. For example, Line 39, the authors could expand the details on previous work in references [11-14]. What kind of the approaches the other researchers used and what the advantages and disadvantages are? In the discussion section, the authors could also compare and validate the results with related work from other researchers.
