Modelling and simulation are important tools during design development processes. For accurate predictions of, e.g. manufacturing processes or final product performance, reliable material data is needed. Usually, the applied models calibrated by utilising direct methods such as conventional uniaxial tensile/compression tests but also inverse occasionally applied. Recently, an effective method, ...

in this study, an extended stress-based forming limit diagram (fld) for prediction of necking based on the marciniak and kucznski (m-k) model is represented and applied in tube hydroforming. the bulge forming of a straight tube is simulated by finite element method and verified with published experimental data. this adaptive simulation technique is based on the ability to detect the onset and g...

Pressurized water reactor (PWR) cores operate under extreme environmental conditions due to coolant chemistry, operating temperature, and neutron exposure. Extending the life of PWRs requires detailed knowledge of the changes in mechanical and corrosion properties of the structural austenitic stainless steel components adjacent to the fuel (internals) that are inherent to such conditions. This ...

Abstract Accurately predicting the fractures that occur in materials during forming not only improves quality, but also reduces amount of material is discarded. Therefore, as a key technology for digital transformation to achieve carbon neutrality, it necessary improve accuracy analysis and establish an efficient method limits. Formability assessment typically performed using ductile fracture c...
