The hydraulic bulge test (HBT) is an important experimental technique to identify the properties of materials and, in particular, metals. One main advantages such technique, testing metals, possibility reaching high levels deformation before fracture. Moreover it allows investigation a biaxial loading condition. A hemispherical can be performed using mechanical punches or pressure fluid. When u...

Material mismatch effect on the cracking behavior is an important topic for those welding structures. Characterization of material constraint based rigorously asymptotic solution studied in this paper. Based decomposition second order term, characterization parameter decomposed as and geometry parameter. In general, total level crack tip under undermatch condition higher than overmatch conditio...
