Modelling Viscous Flow and Elastic Deformation in Fold-Thrust Belts and Magmatic Intrusions
… the emplacement of fluid magma, to the viscous deformation of mountain ranges on the longest time scales. Understanding these processes presents a challenge to traditional modelling techniques. However, simplifying models of the leading-order features of the flow can give insight into the …

A Study of the Physical Properties of Latex as Related to Orthodontic Tooth Movement
Latex elastics have long been used in orthodontics, and force decay has always been a disadvantage. Reports differ on the load-deflection properties of rubber. Decay in elastic bands has ranged from 8% to 74.9%, depending on test conditions. A study was designed to ascertain (1) whether better …

Roll pressure distribution in strip rolling.
… load are determined from consideration of the elastic deformation of the rolls during operation. By interrupting a rolling pass before completion, the shapes of the deformed rolls are imparted to the workpiece surface. Accurate measurement of the imparted profiles at several sections across the …

Form-finding of elastic gridshells
Elastic gridshells are obtained by elastic deformation of an initially flat grid into a three-dimensional shell-like geometry and were first implemented in architecture in the 1970's. Their mechanical behaviour, which includes aspects of both a continuous shell and a network of elastic rods, is …

A Mathematical Discussion of Corotational Finite Element Modeling
… similar corotational methods analyse non-linear deformation of a body by its discretization into finite elements, each with an orthogonal frame rotating (and translating) with the element. Such methods are well suited to deformations where non-linearity arises from rigid body deformation but …

Numerical and Experimental Study of Rock Fracture Creep Under Dry Conditions
… of Musandam limestone (a reservoir rock). The elastic and strength properties of Musandam limestone were obtained from triaxial and indentation tests. The results indicate that linear elasticity and von Mises plasticity can reasonably well describe the contacting asperity deformation. Then, …

Tension regulation in a metal rolling mill
… is derived for two conditions, first with only elastic deformation in the strip, and second with plastic flow in the strip resulting from reduction in the roll bite. The resulting transfer function consists of the one developed for elastic deformation with a degenerative feedback around it. This …

Variational Principles in Finite Elasticity With Applications
… type is derived. Trial functions for the actual deformation gradient are used in the formulation of the principle. Corresponding principles for elastic bodies subject to kinematical constraints such as incompressibility are formulated. The same approach can be used to obtain variational …

Effective Thermal Properties of Granular Porous Media: A Numerical Study using Lattice Blotzmann Methods
… in the pore space. We also incorporate elastic deformation of grains based on an existing model, which depicts the surface topology of grains as a self-affine fractal function. This elastic deformation is a function of Young's modulus of the grains and the external compressing pressure. …

Compressive Creep of a Lightweight, High Strength Concrete Mixture
… loads result in an instantaneous recoverable elastic deformation and a slow, time dependent, inelastic deformation called creep. Creep without moisture loss is referred to as basic creep and with moisture loss is referred to as drying creep. Shrinkage is the combination of autogeneous, drying, …

Remote Sensing of 21st Century Water Stress for Hazard Monitoring in California
… This groundwater overdraft has led to poroelastic compaction of the aquifer system and subsidence of the land surface. Water mass loss also causes elastic deformation of the solid Earth, an opposite and smaller amplitude response than the poroelastic deformation of aquifer systems. These …

Three-dimensional multi-scale hydraulic fracturing simulation in heterogeneous material using Dual Lattice Model
… normal springs govern the macroscopic bulk deformation while shear springs govern the macroscopic distortion. There is fluctuation of stresses even under uniform loading which is one of the characteristics of a lattice model. The magnitude increases with the stiffness ratio of shear spring …

Matrix-fiber stress transfer in composite materials elasto-plastic model with an interphase layer
… fiber break. This scheme takes into account the elastic-plastic behavior of both the matrix and the interphase, and it includes the treatment of stress concentration near the discontinuities of the fibers. The radius of the fibers and the mechanical properties of the matrix were varied in order …

Fracture Behavior of Masonry Bond
The applied fracture mechanics model, when both elastic and inelastic deformations were considered, always over-estimated the post-peak behavior. However, the post-peak behavior was successfully predicted when the model was modified to consider only elastic deformation. The analysis indicated that …

GPGPU-Enabled Physics Based Deformed Model Simulation
… parallel implementation for simulating large elastic deformation. Classic modal analysis provides a set of orthonormal bases vectors, which span a spectral space encoding the dynamics of the elastic body. As each basis vector is orthogonal to each other, the computation is completely decoupled …

Spec2Fab : a reducer-tuner model for translating specifications to 3D prints
… problem have been explored (e.g., appearance or elastic deformation), but they exist as isolated, monolithic algorithms. In this research, I propose an abstraction mechanism that simplifies the design, development, implementation, and reuse of these algorithms. The solution relies on two new data …
