An assessment of phase field fracture: crack initiation and growth

Dear iMechanicians,

We have contributed to the Special Issue organised by the Royal Society on occasion of the centenary of Griffith's seminal paper with a paper revisiting phase field fracture methods and their connection with conventional fracture mechanics theory. I hope that you find it of interest. (https://royalsocietypublishing.org/doi/10.1098/rsta.2021.0021)

Computing wrinkling and restabilization of stretched sheets based on a consistent finite-strain plate theory

It was reported both in experiments and computations using some classical plate theories that wrinkles can appear in a uniaxially stretched rectangular hyperelastic film with clamped-clamped boundaries and can be suppressed upon further tension. Here, based on a recently-available consistent finite-strain plate theory, we investigate this complex instability problem with isola-center bifurcation (the nontrivial solution curve begins and ends at two distinct points on the trivial line) in more depth and present an efficient numerical algorithm.

Critical thresholds for mode-coupling instability in viscoelastic sliding contacts

Mode-coupling instabilities are known to trigger self-excited vibrations in sliding contacts. Here, the conditions for mode-coupling (or "flutter") instability in the contact between a spherical oscillator and a moving viscoelastic substrate are studied. The work extends the classical 2-Degrees-Of-Freedom conveyor belt model and accounts for viscoelastic dissipation in the substrate, adhesive friction at the interface and non-linear normal contact stiffness as derived from numerical simulations based on a boundary element method capable of accounting for linear viscoelastic effects.
