Dear people,

I am currently seeking to determine the shape functions, stiffness, and mass matrices utilizing the Galerkin method and Hermitian shapes, while also taking into account the length scale in modified couple stress theory. Unfortunately, I have been unable to locate a reference that clearly outlines the calculation of these matrices.

I kindly request your assistance in identifying a suitable reference that addresses this specific topic. Your guidance and expertise in this matter would be greatly appreciated.

Thank you for your time and consideration.

Sincerely, Hamid Javaheri
