Fatigue Life Prediction for Component with Local Structural Discontinuity Based on Stress Field Intensity
The impact of notch is one of the major problems that remain to be solved when predicting fatigue life. The zone of notch root has serious stress concentration condition. Stress field intensity (SFI) approach ...

Coupled Non-Fickian Diffusion and Large Deformation of Hydrogels
Solvent migration in swelling polymer shows complex behaviour, as the interface of wet (rubbery) region moves along with solvent diffusion into the dry (glassy) region, which is accompanied by local deformatio...

Study of Damage Evolution in High Strength Al Alloy using X-Ray Tomography
Many micromechanics-based damage models were developed to mimic the macroscopic response of materials through matching measures such as toughness and failure strain [1]. However, there is a lack of microstruct...

Multiscale Characterization of Water-, Oil- and UV-Conditioned Shape-Memory Polymer under Compression
Shape memory polymers (SMPs) are an emerging class of active polymers that may be used for reconfigurable structures on air vehicles. In this study, epoxy-based SMPs were conditioned separately in simulated se...

Crack Initiation, Kinking and Nanoscale Damage in Silica Glass: Multimillion-Atom Molecular Dynamics Simulations
We present molecular dynamics (MD) simulations of crack kinking, growth, propagation and healing at the nanometer scale in a confined, pre-cracked silica glass subjected to dynamic mode II loading. The pre-cra...

Creep Instability of Spinning Viscoelastic Rod
In this paper, A general theory for studying dynamic instability of viscoelastic spinning rod (shaft, arm etc.) is presented. The continuous and multi-degree-of-freedom(MDOF) discrete model are both considered...

Hybrid Ray-Mode and Wavefront-Resonance Techniques for Acoustic Emission and Scattering in Multiwave Layered Media
Analytical modeling of acoustic detection of flaws in composite laminates poses a difficult problem in wave propagation and scattering. Wave excitation and propagation in the laminate itself is complicated by ...

On the Relationship between the Geometry of Deformed Crack Tip and Crack Parameters
An experimental investigation into the relationship between fracture mechanics parameters (J integral and crack tip opening displacement) determined by mechanics tests and geometrical parameters of deformed cr...
