The interaction between stress fields at the crack-tip and nearby microstructural
heterogeneities influences the crack path, and in turn, the effective fracture toughness of a …

The cohesive zone law represents the constitutive traction versus separation response
along the crack-tip process zone of a material, which bridges the microscopic fracture …

The presence of microstructural defects resulting in unpredictable failure behavior has
limited the use of additively manufactured (AM) metals in structural applications. In addition …

Beyond pressure-sensitivity, plastic deformation of glassy polymers exhibits intrinsic
softening followed by progressive rehardening at large strains. This highly nonlinear stress …

In this work we investigate the relationship between the different microstructural features in
additively-manufactured (AM) Direct Metal Laser Deposited Ti–6Al–4V alloys and the …

Hydrostatic stress can affect the non-elastic deformation and flow stress of polymeric
materials and certain metallic alloys. This sensitivity to hydrostatic stress can also influence …

Microstructures with two distinct size-scales of voids are commonplace in additively-
manufactured metals. The smaller-scale voids nucleate from inclusions within the metal …

This paper presents a comprehensive review and comparison of different theories and
models for water vapor pressure under rapid heating in moisture permeable materials, such …

Unlike micromechanics failure models that have a well-defined crack path, phase-field
fracture models are capable of predicting the crack path in arbitrary geometries and …

Continuum models of porous media have revolutionized computational fracture mechanics
for traditional ductile materials, but the inherent assumptions have limited generalizability to …
