Formation of Multiscale <strong>and</strong> Multistage Fracture Process<br />
Macro deformation (contour of macro effective strain)<br />
(a) Void growth<br />
(primary voids)<br />
Micro deformation (contour of micro effective strain)<br />
(a) Development of<br />
micro deformation<br />
(b) Intense deformation at<br />
ligament between voids<br />
(b) Microvoid sheeting (c) Microvoid shear<br />
coalescence<br />
(c) Initial macro crack (d) Macro crack propagation<br />
Arising from the Strong Interaction between Micro <strong>and</strong> Macro Deformations<br />
(d) Further Microvoid shear<br />
coalescence<br />
I. Multiresolution modeling across multi‐scale of microstructures (voids)<br />
II. Concurrent modeling considering interaction across microstructures has been achieved<br />
(Though there are many primary <strong>and</strong> secondary particles involved)
