PhD Position: Multiscale modeling of size effects in the fracture of soft solids

The Laboratory of Soft and Living Materials at the Department of Materials is seeking a PhD candidate.

Job description

Owing to its scale-spanning nature from individual monomers to complex polymer networks, fracture in soft materials vastly differs from classical theories and requires accounting for the effects of nonlinearity, irreversibility, nonlocality and possibly multiple phases. As one consequence, strong size effects have recently been observed in the fracture of soft solids when descending to small scales. Experiments have indicated a transition in failure mechanisms and in the geometry of failure process zones, when decreasing the crack size below a characteristic length scale. The causal mechanisms - and, more generally, a fundamental understanding of fracture in soft solids across length scales - have remained widely unexplored but are key to fully exploiting novel classes of soft materials. The objective of this PhD project is to establish a new multiscale theory and associated numerical tools for a complete fundamental understanding of fracture in soft solids across length scales. This will be achieved through a bottom-up multiscale approach, taking crosslinked silicone elastomers as a model system.

The PhD project will be hosted within the Laboratory of Soft and Living Materials in the Department of Materials, where the experiments inspiring these questions are being performed. This offers a unique opportunity to work in a multidisciplinary team with tight feedback between experiment and theory.

The starting date is October 2020.
