Dear researchers,
I am currently researching the issue of fracture in thin steel plates containing holes. Some scholars have already conducted static tensile fracture tests on plates with holes [1], and the test model is shown in the attachment. I have derived the stress distribution field under static tensile conditions. However, in my practical applications, the specimen is subjected to high loading rates, where the tensile force approximates an impulse force. Therefore, the static results can only serve as a reference. I would like to further investigate the fracture mechanisms in the transient tensile behavior of the steel plate, including the influence of the distribution of cracks near the hole and hole geometry on the results. It would be ideal to obtain theoretical solutions. Could you provide me with some suggestions or references regarding the research direction? Thank you for your attention.

Hi
Experimental and numerical methods can be used to investigate transient fracture mechanisms and crack distribution in thin steel plates with holes under high loading.
In the experimental method, it is possible to check the mechanical behavior of the steel plate under high loading by using tensile and bending tests. These tests can help identify weak points and fractures in the steel plate.
In the numerical method, finite element modeling software can be used to simulate the mechanical behavior of steel plates under high loading. These simulations can help us identify transient failure mechanisms and crack distribution in perforated steel plates under high loading.
In both experimental and numerical methods, equipment such as electron microscopes and digital imaging tools can be used to investigate transient failure mechanisms and crack distribution. By using these tools, it is possible to identify weak points and fractures in steel plates more precisely.
On the other hand, to investigate transient failure mechanisms and crack distribution in steel plates with holes, the necessary precautions must be taken in terms of safety and hygiene. For example, safety clothing and masks must be used, and safety devices must also be used to perform tests.
