The work is dedicated to determination of stress-strain behavior of Ti6Al4V alloy deformed in conditions of biaxial tension provided by free bulging testing. The dome height during each test was continuously measured and recorded using a magnetostrictive position transducer. All the tests were performed using stepped pressure regime with jump pressure changing between two values ...

In this study, the rheological characteristics of a titanium alloy have been obtained by
multi-dome bulging test. Free bulging process is an experimental technique that can be used to
characterize material in conditions of biaxial tension during superplastic, as well as conventional,
hot forming. The constitutive constants are calculated on a base of the information about the bulge
geometry, ...

Free bulging process is an experimental technique which can be used to characterize a sheet material in conditions of biaxial tension during hot forming. Analytical and semi-analytical models of this process are usually based on the hypothesis offering certain relations between the geometrical characteristics of a bulge during forming. The paper presents an original relation ...

Determination of material constants describing its behavior during superplastic gas
forming is the main subject of this study. The main feature of free bulging tests is the stress-strain
conditions which are very similar to ones occurring in the most of gas forming processes. On the
other hand, the interpretation of the results of such tests is a complicated ...

This work is devoted to the investigation of the thickness-height dependence of the freely molded dome. The series of simulations were produced by finite element method. The generalization of the simulation results allowed us to obtain an analytical thickness-height relation of the dome ...

The paper presents a simple technique for the characterization of materials superplasticity by free bulging tests, which is based on inverse analysis. The main idea of this technique is a semianalytical solution of the direct problem instead of finite element
simulation which allows one to reduce the calculation time significantly. Presented method use experimental time-thickness and ...
