Including a pressure dependent relation between static and dynamic elastic moduli in a Finite Element deformation model of Grímsvötn Volcano, Iceland

Volcanica
Surface deformation is an important tool for studying active volcanoes. Numerical deformation models can consider irregular features like crustal heterogeneity and avoid biases due to oversimplification. Dynamic elastic moduli can be derived from seismic

Rock Physical Modeling of Tight Sandstones Based on Digital Rocks and Reservoir Porosity Prediction From Seismic Data

Frontiers in Earth Science, 2022
Digital rock physics (DRP) has become an important tool to analyze the characteristics of pore structures and minerals and reveal the relationships between microscopic structures and the physical properties of reservoirs. However, it is greatly difficult

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Quadratic invariants of elastic moduli

, 2006
A quadratic invariant is defined as a quadratic form in the elements of a tensor that remains invariant under a group of coordinate transformations. It is proved that there are 7 quadratic invariants of the 21-element elastic modulus tensor under SO(3 ...

The closest elastic tensor of arbitrary symmetry to an elasticity tensor of lower symmetry [PDF]

, 2006
The closest tensors of higher symmetry classes are derived in explicit form for a given elasticity tensor of arbitrary symmetry. The mathematical problem is to minimize the elastic length or distance between the given tensor and the closest elasticity ...

Bridging between material properties of proteins and the underlying molecular interactions.

PLoS ONE, 2021
In this work, we develop a novel method that bridges between material properties of proteins, particularly the modulus of elasticity, and the underlying molecular interactions. To this end, we employ both an all-atom normal mode analysis (NMA) model with

Elastic moduli approximation of higher symmetry for the acoustical properties of an anisotropic material

, 2006
The issue of how to define and determine an optimal acoustical fit to a set of anisotropic elastic constants is addressed. The optimal moduli are defined as those which minimize the mean squared difference in the acoustical tensors between the given ...

Elastic Moduli of Carbon Nanohorns [PDF]

Journal of Nanomaterials, 2011
Carbon nanotube is a special case of carbon nanohorns or carbon nanocones with zero apex angle. Research into carbon nanohorns started almost at the same time as the discovery of nanotubes in 1991. Most researchers focused on the investigation of nanotubes, and the exploration of nanohorns attracted little attention.
