Researches regarding the relation forces – deformations on extensible elastic diaphragm chuck with jaws

Résumé

The paper presents an analysis, of plane stress and deformation, of elastic diaphragms that are used on elastic diaphragm chuck with jaws. A comparison, of induced stress and deformations, study was made by using the relations from different sources. In consideration of relations that describe induced stress and deformation on plan, circular, embedded, plate, loaded with a concentrated force and current knowledge regarding jaws, elastic, membrane, mechanisms. For the verification of the results obtained, was used the Finite Element Method. The result obtained by using the finite element analysis, led on the conclusion that, the values for maximum stress calculated by using the mathematical model for Fixtures are closer than the results obtained form model.
