Identification of two-dimensional prestress fields in inhomogeneous plates [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2023 Based on the model of in-plane oscillations of inhomogeneous prestressed plates, the new inverse problems of identifying the components of the prestress tensor via acoustic response probing are considered for the plates with and without holes and ...
