Performance Evaluation and Durability Studies of Adhesive Bonds
… joints containing patterns of discreet localized weak interfaces created using physical vapor deposition of copper. In a DCB specimen tested under mode-I conditions, fracture energy within the patterned regions scaled according to a simple rule of mixture, while reverse R-curve and R-curve type …

Toughening mechanisms in weak matrix ceramic composites
… matrix composites is closely related to the weak interface between fiber and matrix. The weak interfaces in composites have been provided by reducing the chemical bonding and the residual thermal stresses between constituents. A new way to introduce the weak interface by induced porosity or …

Analytics-Driven Cooperative Multi-Robot Additive Manufacturing: Advancing Efficiency and Quality
… systems, where decomposition creates weak interfaces, thesis proposes a Synchronous Multi-Layer Printing strategy that recovers the joint strength of single-head deposition while preserving the throughput of multi-head printing; for multi-laser systems, the thesis establishes a …

Unveiling the mechanical behavior of the rod-like microstructure in the radular teeth of cryptochiton stelleri
… mineralized materials that are surrounded by a weak organic interface combine the stiff mechanical behavior of building blocks, like hydroxyapatite or aragonite, and the compliance of the organic surroundings. Unique mechanical properties (e.g. light density and toughness) distinguish …

Algebraic level sets for CAD/CAE integration and moving boundary problems
… (or<em>moving boundary problems</em>), interfaces or cracks, blending functions are used to enrich the underlying domain with the known behavior on the enriching entity. The blending functions are typically dependent on the distance from the evolving boundaries. For boundaries defined by …

Interactions of Cellulose Nanocrystals in Colloidal and Composite Systems
… fillers which can be implemented such that the weak interfaces with polymer matrices can be bridged with fillers providing reinforcement over a broader length scale.

Crack path selection and shear toughening effects due to mixed mode loading and varied surface properties in beam-like adhesively bonded joints
… with uniform bonding, and those with locally weakened interfaces. When removing cured components from molds, interfacial debonds can sometimes initiate and propagate along both mold surfaces, resulting in the molded product partially bridging between the two molds and potentially being damaged …
