Abstract
The task of analysing the large deflections in a square diaphragm is solved. The analytical expressions for presence of deflections in a square diaphragm are assessed in view of deformation of the middle of a plane. The simple algorithms of defining a component tensor of strain are given. Good agreement between experimental and analytical results for the diaphragm are demonstrated. Nonlinear strain and relative changes of resistance of longitudinal and cross resistors on a diaphragm are calculated
