The Triaxiality Effect on Damage Evolution in Al-2024 Tensile Samples
MetalsThe effect of triaxiality on the evolution of damage in Al-2024 aluminum cylindrical specimens is studied in this work. Uncoupled and coupled damage models, all of them explicitly dependent on triaxiality, are assessed and compared.

Mechanical Behaviour of Dual Phase Steels under Different Strain Rates [PDF]
Kemija u Industriji, 2023 The objective of this research was to analyse the stress and strain behaviours of the triaxiality specimens (specimens of different shaping) of dual-phase steels, respectively DP600 and DP800, whose microstructures mainly comprise ferrite and martensite ...

Effect of triaxial stress distribution upon roughness of brittle fracture surface [PDF]
MATEC Web of Conferences, 2019 To observe the effect of stress triaxiality upon brittle fracture surface, we performed two types of experiments which differ in stress triaxiality. As a result, crack branch starting speed changes in two specimens and the speed was affected by stress ...

On the damage behaviour in dual-phase DP800 steel deformed in single and combined strain paths
Materials & Design, 2023 Ductile damage in dual-phase steels deteriorates the mechanical properties, resulting in a lowered crashworthiness and a shorter life-time under cyclic loading. However, most works focus on the observation of damage under simple strain paths, even though
