The effect of residual stresses arising from laser shock peening on fatigue crack growth [PDF]

, 2010
Residual stresses have in the past been introduced to manipulate growth rates and shapes of cracks under cyclic loads. Previously, the effectiveness of shot peening in retarding the rate of fatigue crack growth was experimentally studied.

Introduction of a fretting-fatigue mapping concept: Development of a dual crack nucleation - crack propagation approach to formalize fretting-fatigue damage [PDF]

, 2009
Fretting-fatigue induced by combined localized cyclic contact motion and external bulk fatigue loadings may result in premature and dramatic failure of the contacting components.

Tree-width for first order formulae [PDF]

, 2012
We introduce tree-width for first order formulae φ, fotw(φ). We show that computing fotw is fixed-parameter tractable with parameter fotw. Moreover, we show that on classes of formulae of bounded fotw, model checking is fixed parameter tractable, with ...

Fractal-Based Non-Linear Assessment of Crack Propagation in Recycled Aggregate Concrete Using 3D Response Surface Methodology

Fractal and Fractional
This study investigates the fracture behavior of recycled aggregate concrete by integrating fractal theory and empirical modeling to quantify how recycled coarse aggregates (RCAs) and recycled fine aggregates (RFAs) influence crack complexity and maximum
