Size scaling of strength in thin film delamination
, 2011 We investigate by numerical simulation the system size dependence of the shear delamination strength of thin elastic films. The films are connected to a rigid substrate by a disordered interface containing a pre-existing crack. The size dependence of the

Effect of Disorder and Notches on Crack Roughness [PDF]
, 2007 We analyze the effect of disorder and notches on crack roughness in two dimensions. Our simulation results based on large system sizes and extensive statistical sampling indicate that the crack surface exhibits a universal local roughness of $\zeta_{loc}

Fatigue crack propagation in microcapsule toughened epoxy [PDF]
, 2004 The addition of liquid-filled urea-formaldehyde (UF) microcapsules to an epoxy matrix leads to significant reduction in fatigue crack growth rate and corresponding increase in fatigue life.

Fracture Mechanical Behavior of Cracked Cantilever Roof with Large Cutting Height Mining
Shock and Vibration, 2020 Accurately predicting the roof collapse span is crucial in ensuring the safe production of thick seam mining with large mining height, which is easy in forming a “cantilever beam” structure.

On the exceptional damage-tolerance of gradient metallic materials [PDF]
, 2020 An experimental study is described on the fracture toughness and micro-mechanisms associated with the initiation and propagation of cracks in metallic nickel containing marked gradients in grain size, ranging from ∼30 nm to ∼4 μm.

Resonant Scattering and Crack Sizing
, 1985 Theoretical consideration of ultrasonic scattering from interior cracks has received considerable attention in recent years. These studies have led to scattering amplitude computations for ultrasonic backscatter from circular cracks by the method of optimal truncation (MOOT) (1, 2) and by T-matrix techniques (3).

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.

Local dynamics of a randomly pinned crack front during creep and forced propagation: An experimental study [PDF]
, 2011 We have studied the propagation of a crack front along the heterogeneous weak plane of a transparent poly(methyl methacrylate) (PMMA) block using two different loading conditions: imposed constant velocity and creep relaxation.
