WebJan 1, 1991 · A non-linear analytical theory for calculating the deformation and stress in the bossed square diaphragm is derived. For a theoretical consideration, the bossed square diaphragm is approximated by a plate strip extended infinitely in one direction, as is depicted in Fig. 2. Thus the three-dimensional problem can be reduced to two dimensions. WebOn the front side of the diaphragm, four grooves were etched by reactive iron etching (RIE) to form an octagonal bossed pattern. Each two grooves were separated by a rib …
