SH Wave Scattering and Dynamic Stress Concentration in Piezomagnetic Materials with Non-Circular Openings

Round 1

Reviewer 1 Report

The manuscript is written well and owing to few issues minor revision is needed.

1. How does the piezo-magnetism supports SH wave scattering and dynamic stress?

2. What are the boundary conditions for circular and non-circular openings?

3. Explain the piezomagnetic materials used in this work.

4. Is there any relation between elasticity and piezo-magnetism?

5.  How does the permeability affect the boundary conditions and modal coefficients?

6. What is novelty and motivation behind the work?

7. Use some more references supporting the work.

moderate corrections are required.

Reviewer 2 Report

This article utilizes complex functions and wave function expansion methods to study the scattering and DSCC issues of steady-state SH waves in piezoelectric materials with non-circular openings. The research findings indicate that the shape of the opening, the incident wave number, and the incident angle significantly impact this structure. Compared to the theory of elastic media, this method successfully generalizes the mature theory of elastic piezoelectric media to this field, providing a new approach for analyzing the dynamic problems of piezoelectric materials. This paper is well written and can be accepted for publication in its present form. Some question should be classified.

(1)     The author said “The DSCC in specific areas can be much higher than in other places, making them more prone to damage.”. How to avoid damage?

(2)     The language should be improved.

(3)     The author said “In most cases, the DSCC produced by low-frequency waves is higher than that produced by high-frequency waves.”. Why does this happen?

Reviewer 3 Report

The article is about the study of SH wave scattering and dynamic stress concentration in piezomagnetic materials with non-circular openings.  Authors focus on elliptical openings and analyze the effects of different incident angles and dimensionless wave numbers on the dynamic stress concentration coefficients. They find that the dynamic stress concentration coefficient is positively correlated with the illumination region of elliptical openings, and that low wave numbers have a more significant influence. They suggest that elastic dynamic analysis of non-circular defects in low-frequency environments is important for enhancing the performance and reliability of piezomagnetic materials. 

 

In my opinion, this paper is prepared carefully and well presented. Thus, I think this paper can be published on this journal. 

I only have one question, could you please provide more examples for piezomagnetic materials. I noticed your research is base on NiFe2O4.
