Efficient meshless phase-field modeling of crack propagation by using adaptive load increments and variable node densities
Izaz Ali, Božidar Šarler, Boštjan Mavrič
Izvirni znanstveni članek
Oznake: phase-field method;strong-form meshless method;LRBFCM;adaptive load step size;scattered nodes;PH_;
This study employs the fourth-order phase-field method (PFM) to investigate crack propagation. The PFM incurs significant computational costs due to its need for a highly dense node arrangement for accurate crack propagation. This study proposes an adaptive loading step size strategy combined with a ...

Izaz Ali, Gašper Vuga, Boštjan Mavrič, Umut Hanoglu, Božidar Šarler
Objavljeni znanstveni prispevek na konferenci
Oznake: brezmrežne metode;fazno polje četrtega reda;meshless methods;fourth-order phase-field;
The prediction of crack propagation in fracture mechanics is still a fundamental challenge. In recent decades, phase-field formulation emerged as a powerful tool for the simulation of crack evolution, which offers a continuous representation of cracks from intact to broken material. For the first ti ...
