Vulnerable Window of Yield Strength for Swelling-Driven Fracture of Phase-Transforming Battery Materials
Ataollah Mesgarnejad, Alain Karma
Despite numerous experimental and theoretical investigations of the mechanical behavior of high-capacity Si and Ge Li-ion battery anodes, our basic understanding of swelling-driven…
Phase Field Modeling of Chemomechanical Fracture of Intercalation Electrodes: Role of Charging Rate and Dimensionality
Ataollah Mesgarnejad, Alain Karma
We investigate the fracture of Li-ion battery cathodic particles using a thermodynamically consistent phase-field approach that can describe arbitrarily complex crack paths and cap…
Phase-Field Models for Fatigue Crack Growth
Ataollah Mesgarnejad, Anahita Imanian, Alain Karma
We introduce a class of models based on near crack tip degradation of materials that can account for fracture growth under cyclic loads below the Griffith threshold. We incorporate…
Crack Path Selection in Orientationally Ordered Composites
Ataollah Mesgarnejad, Chunzhou Pan, Randall M. Erb +2
While cracks in isotropic homogeneous materials propagate straight, perpendicularly to the tensile axis, cracks in natural and synthetic composites deflect from a straight path, of…
