A quick-release door closure design (Bandlock 2) is described. The paper presents a case study of the design and analysis of an existing closure geometry. Four techniques for stress analysis of the closure are described: two numerical (finite element and boundary element) an experimental (electrical resistance strain gauge) and an approximate (strength of materials) approach to the calculation of stresses. The stress results are presented in an unnormalized form for an ANSI class 600 test pressure.
