Layer-by-Layer Printing of Photopolymers in 3D: How Weak is the Interface? [PDF]

open access: yesACS Applied Materials & Interfaces, 2020
Additive manufacturing or, as also called, three-dimensional (3D) printing is considered as a game-changer in replacing traditional processing methods in numerous applications; yet, it has one intrinsic potential weakness related to bonding of layers ...

Effects of Weak Layer Angle and Thickness on the Stability of Rock Slopes [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2016
This paper researches two key factors (angle and thickness) of a weak layer in relation to their influencing mechanism on slope stability. It puts forward the sliding surface angle and morphological model criteria for the control of rock slopes and ...

Temporal evolution of crack propagation propensity in snow in relation to slab and weak layer properties [PDF]

open access: yesThe Cryosphere, 2016
If a weak snow layer below a cohesive slab is present in the snow cover, unstable snow conditions can prevail for days or even weeks. We monitored the temporal evolution of a weak layer of faceted crystals as well as the overlaying slab layers at the ...

Modeling snow slab avalanches caused by weak layer failure – Part I: Slabs on compliant and collapsible weak layers [PDF]

open access: yes, 2019
. Dry-snow slab avalanche release is preceded by a fracture process within the snowpack. Recognizing weak layer collapse as an integral part of the fracture process is crucial and explains phenomena such as whumpf sounds and remote triggering of ...

Experimental Study on the Propagation Law of Explosive Stress Wave in Cement Mortar with Weak Layers

open access: yesBuildings, 2022
The weak layer has good attenuation performance when it comes to the explosive stress wave, which can be used in protective structures. In this paper, a cement mortar specimen was designed, cast, and tested. Under inner explosion, due to the expansion of

Seismic Response and Damage Characteristics of RCC Gravity Dams Considering Weak Layers Based on the Cohesive Model

open access: yesMathematics, 2023
Due to the construction technology of roller compacted concrete (RCC) gravity dams, there are many weak layers that have the potential to affect the seismic performance of dams. However, research on the seismic response and failure characteristics of RCC

Using video detection of snow surface movements to estimate weak layer crack propagation speeds

open access: yesAnnals of Glaciology, 2023
Dry-snow slab avalanches release due to crack propagation in a weak snow layer under a cohesive snow slab. Crack propagation speeds can provide insights into the potential size of avalanches and inform fracture and avalanche release models. Despite their
