Static analysis of functionally graded anisotropic nanoplates using nonlocal strain gradient theory

We study functionally graded nanoplates made of (hexagonal) beryllium crystals. Therefore, a five-variable refined plate theory in conjunction with the nonlocal strain gradient theory is developed. From the best knowledge of authors, it is the first time that mentioned theories are developed for hexagonal materials. The governing equations are obtained using Hamilton’s principle where an analytical technique based on Navier’s series is utilized...
