A New Shear Mathematical Model of the Vibration of Porous Functionally Graded Lamellar Accelerometers with Attached Mass in a Temperature Field

A new shear mathematical model is proposed for a lamellar accelerometer made of a porous functionally graded material (PFGM) with an attached mass in a temperature field. The accelerometer consists of lamellar structures, which are lamellas and shallow shells of small curvature. The problem of eigenvalues is solved using the Bubnov-Galerkin method in higher approximations, and numerical examples are provided to support the model.
