*Geckos and Needles: Interesting Observations in Soft Matter Fracture*
Unstable failure is traditionally avoided. However, recently, we have
focused on the distinct advantages of unstable crack propagation at
interfaces and within ultra-soft materials. We highlight two examples
that demonstrate these findings and how they can inform our broad
understanding of soft gels, tissues and organisms.
First, we describe recent experiments focused on demonstrating a scaling
relationship, which relates climbing force to the properties and morphology of
climbing organisms. Second, we discuss new measurements that quantify the
deformation mechanisms associated with puncturing a soft material.We have
initiated a broad study into the mechanics of puncture in synthetic gels and
have discovered several interesting and impactful relationships. For example,
we observe that the nominal stresses prior to puncture can exceed several
hundred times the Young?s modulus.These results and our proposed analysis have
implications on crack nucleation in soft gels.
