The complexity of the material model parameter identification and the consideration of essential behaviours such as temperature dependence or residual strain may be a great challenge during the constitutive modelling. As a consequence of the Mullins effect, the damage induced anisotropy may also appear. A detailed review of the direction-dependent energy dissipation can be found in [9–12]. The break of...

The novelty of the analysis approach lies in direct comparison of experimental and numerical results in scale 1:1 – both in macroscale and microscale. The analysis indicated the most sensitive points of the studied columns in terms of damage initiation. The comparison of experimental failure analysis and finite element method showed that the PFA model predicts the approximate localization of...

The fluid dynamics of occluded arteries depends on many physiological factors and the resulting complexity of the post-stenotic flow field present a challenge for numerical solvers. Disease of the arteries are globally prevalent and life-threatening.. The main disadvantage of the CFD approach is its inaccuracy, arising from both modelling and numerical origins. [21] are general purpose in design, where, of...

b Mathematical Institute of the Serbian Academy of Sciences and Arts, Kneza Mihaila 36, Belgrade, Serbia. Frequency response curves of the presented nonlinear system are determined by introducing the incremental harmonic balance and continuation method for different values of material parameters. The main feature of the NES is to transfer the mechanical energy from a pri- mary structure to the...

Often the control of the system ’ s behavior is required in the presence of im- pacts [10]. On the other hand, the fuselage of the aircraft causes a soft impact on a robust structure. These models are capable of providing essential information on the outcome of the impact for a certain structural layout of the target and parameter settings...
