Project description
Enhanced understanding of ‘soft fracture’ leads to improved designs
Hard materials such as metals, plastics and composites have been the mainstay of device development. As soft materials increasingly pervade areas like tissue engineering, soft robotics and stretchable electronics, the need has arisen to better characterise their geometrically non-linear fracture mechanics, given that they allow for extremely large deformations. The ERC-funded SoftFrac project will address this need via a combined theoretical, computational and experimental approach. Exploiting the development of ‘configurational mechanics’, SoftFrac will develop a transformational configurational fracture theory and model. Experimental study of the geometrically nonlinear fracture of soft materials will further inform the model and lead to rational and improved design of soft materials to minimise fracture.
Objective
SoftFrac will revolutionise geometrically nonlinear fracture mechanics of soft materials (in short soft fracture) by capitalising on configurational mechanics, an unconventional continuum formulation that I helped shaping over the past decades. Mastering soft fracture will result in disruptive progress in designing the failure resilience of soft devices, i.e. soft robotics, stretchable electronics and tissue engineering applications. Soft materials are challenging since they can display moduli as low as only a few kPa, thus allowing for extremely large deformations. Geometrically linear fracture mechanics is well established, nevertheless not applicable for soft fracture given the over-restrictive assumptions of infinitesimal deformations. The appropriate geometrically nonlinear, finite deformation counterpart is, however, still in its infancy. By combining innovative data-driven/data-adaptive constitutive modelling with novel configurational-force-driven fracture onset and crack propagation, I will overcome the fundamental obstacles to date preventing significant progress in soft fracture. I propose three interwoven research Threads jointly addressing challenging theoretical, computational and experimental problems in soft fracture. The theoretical Thread establishes a new constitutive modelling ansatz for soft in/elastic materials, and develops the transformational configurational fracture approach. The computational Thread provides the associated novel algorithmic setting and delivers high-fidelity discretisation schemes to numerically follow crack propagation driven by accurately determined configurational forces. The experimental Thread generates and analyses comprehensive experimental data of soft materials and their geometrically nonlinear fracture for properly calibrating and validating the theoretical and computational developments. Ultimately, SoftFrac, for the first time, opens up new horizons for holistically exploring the nascent field soft fracture.
