Fracture and Toughening of Mycelium-based Biocomposites

Materials & Design
This study presents a combined experimental and analytical study of the fracture behavior and toughening mechanisms of bioprocessed mycelium-based biocomposites. The composites comprise hemicellulose hemp ducts (as nutritional and reinforcing components)

Phase field modelling of crack propagation, branching and coalescence in rocks

, 2018
We present a phase field model (PFM) for simulating complex crack patterns including crack propagation, branching and coalescence in rock. The phase field model is implemented in COMSOL and is based on the strain decomposition for the elastic energy ...

On stress analysis of a crack-layer [PDF]

This work considers the problem of elastic interaction of a macrocrack with an array of microcracks in the vicinity of the macrocrack tip. Using the double layer potential techniques, the solution to the problem within the framework of the plane problem ...

A holistic review of nanomaterials in strain-hardening cementitious composites: Insights into micro- and macromechanical, deformation, smart, and durability properties

Results in Engineering
Strain-hardening cementitious composites (SHCC) are rapidly gaining popularity as building materials because of their remarkable ductility, increased tensile strain capacity, and controlled saturated microcrack propagation with tight crack width. Careful

Calculation of stress intensity factors in an isotropic multicracked plate: Part 2: Symbolic/numeric implementation [PDF]

Analytical derivations of stress intensity factors (SIF's) of a multicracked plate can be complex and tedious. Recent advances, however, in intelligent application of symbolic computation can overcome these difficulties and provide the means to ...
