The distributional stress–energy quadrupole

Classical and Quantum Gravity, 2020
Abstract We investigate stress–energy tensors constructed from the delta function on a worldline. We concentrate on quadrupoles as they make an excellent model for the dominant source of gravitational waves and have significant novel features.

The Stress Transmission Universality Classes of Periodic Granular Arrays [PDF]

, 2000
The transmission of stress is analysed for static periodic arrays of rigid grains, with perfect and zero friction. For minimal coordination number (which is sensitive to friction, sphericity and dimensionality), the stress distribution is soluble without

Full-field pulsed magneto-photoelasticity – Experimental Implementation [PDF]

, 2006
This paper contains a description of the experimental procedure employed when using a pulsed-magneto-polariscope (PMP) and some initial full-field through-thickness measurements of the stress distribution present in samples containing 3D stresses.

Yield stress fluids method to determine the pore size distribution of a porous medium [PDF]

, 2014
In this paper a new method is presented in order to determine the pore size distribution in a porous medium. This original technique uses the rheological properties of some non-Newtonian yield stress fluids flowing through the porous sample.

Socket shield technique: Stress distribution analysis

Journal of Indian Society of Periodontology, 2023
Background: To analyze through finite element analysis the stress distribution in peri-implant bone tissues, implants, and prosthetic components induced by the socket shield (SS) technique in comparison to other techniques used to treat tooth loss.

Environmental stress influences Malesian Lamiaceae distributions

Ecology and Evolution, 2022
AbstractDual effects of spatial distance and environment shape archipelagic floras. In Malesia, there are multiple environmental stressors associated with increasing uplands, drought, and metal‐rich ultramafic soils. Here, we examine the contrasting impacts of multifactorial environmental stress and spatial distance upon Lamiaceae species distributions.

New model for surface fracture induced by dynamical stress

, 1997
We introduce a model where an isotropic, dynamically-imposed stress induces fracture in a thin film. Using molecular dynamics simulations, we study how the integrated fragment distribution function depends on the rate of change and magnitude of the ...

Stress distribution and the fragility of supercooled melts

, 2010
We formulate a minimal ansatz for local stress distribution in a solid that includes the possibility of strongly anharmonic short-length motions. We discover a broken-symmetry metastable phase that exhibits an aperiodic, frozen-in stress distribution ...

Effect of high-pressure rolling followed by laser processing on mechanical properties, microstructure and residual stress distribution in multi-pass welds of 304L stainless steel [PDF]

, 2016
Multi-pass fusion welding by a filler material (wire) is normally carried out to join thick steel sections used in most engineering applications. Multiple thermal cycles from a multi-pass weld resulted in a variable distribution of residual stress field ...

Avalanches, precursors and finite size fluctuations in a mesoscopic model of amorphous plasticity [PDF]

, 2011
We discuss avalanche and finite size fluctuations in a mesoscopic model to describe the shear plasticity of amorphous materials. Plastic deformation is assumed to occur through series of local reorganizations.
