1. A novel contact force model was developed for the impact analysis of structures with coating.
2. The model was experimentally verified to accurately predict the contact force between two surfaces.
3. The model can be used to improve the accuracy of impact analysis in engineering applications.
The article is generally reliable and trustworthy, as it provides a detailed description of the research conducted and presents evidence to support its claims. The authors provide a clear explanation of their methodology and results, which makes it easy to understand their findings. Additionally, they cite relevant literature to back up their claims and provide an extensive list of references at the end of the article.
However, there are some potential biases that should be noted. For example, the authors do not discuss any potential risks associated with using their model or any possible limitations that could affect its accuracy. Additionally, they do not explore any counterarguments or present both sides equally when discussing their findings. Furthermore, there is no mention of how this research could be applied in practical engineering applications or what implications it may have for future research in this field.
