Computational modelling of hydrogen assisted fracture in polycrystalline materials
A. Valverde-González, E. MartÃnez-Pañeda, A. Quintanas-Corominas +2
We present a combined phase field and cohesive zone formulation for hydrogen embrittlement that resolves the polycrystalline microstructure of metals. Unlike previous studies, our…
Node-to-segment and node-to-surface interface finite elements for fracture mechanics
M. Paggi, P. Wriggers
The topologies of existing interface elements used to discretize cohesive cracks are such that they can be used to compute the relative displacements (displacement discontinuities)…
Crack arrest through branching at curved weak interfaces: an experimental and numerical study
M. T. Aranda, I. G. Garcia, J. Reinoso +2
The phenomenon of arrest of an unstably-growing crack due to a curved weak interface is investigated. The weak interface can produce the deviation of the crack path, trapping the c…
Identification of higher-order continua equivalent to a Cauchy elastic composite
A. Bacigalupo, M. Paggi, F. Dal Corso +1
A heterogeneous Cauchy elastic material may display micromechanical effects that can be modeled in a homogeneous equivalent material through the introduction of higher-order elasti…
Inkjet Printed 2D-Crystal Based Strain Gauges on Paper
C. Casiraghi, M. Macucci, K. Parvez +6
We present an investigation of inkjet printed strain gauges based on two-dimensional (2D) materials. The technology leverages water-based and biocompatible inks to fabricate strain…
A consistent interface element formulation for geometrical and material nonlinearities
J. Reinoso, M. Paggi
Decohesion undergoing large displacements takes place in a wide range of applications. In these problems, interface element formulations for large displacements should be used to a…
