Elastic fracture in random materials

Physical Review B, 1988
We analyze a simple model of elastic failure in randomly inhomogeneous materials such as minerals and ceramics. We study a two-dimensional triangular lattice with nearest-neighbor harmonic springs. The springs are present with probability p. The springs can only withstand a small strain before they fail completely and irreversibly.

Nonlinear elasticity in nanostructured materials

Reports on Progress in Physics, 2011
We elaborate on a blended continuum/atomistic theoretical picture of the nonlinear elastic properties of nanostructured materials, looking at diverse aspects such as dispersions of inhomogeneities within a matrix, random or graded nanograined materials, two-dimensional atomic sheets.

Elastic‐plastic materials as simple materials

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1973
AbstractA theory including classical elastic‐plastic materials is derived as a special case of the theory of simple material under certain hypotheses of smoothness and rate‐independence. The concepts of yield functions and flow rules of the classical theories are shown to be defined by the stress functional of a simple material under these smoothness ...

A Class of Hypo-Elastic Non-Elastic Materials and their Thermodynamics

Archive for Rational Mechanics and Analysis, 1984
The authors study thermo-hypo-elastic equations and demonstrate that this equations are consistent with the first and second laws of thermodynamics. They obtain this equations by using the standard thermodynamical technique. The hypo-elastic equations which result in isothermal limit \((\dot T=0)\) admit no elastical solutions.

Elastic and plastic properties of elastic dental impression materials

Dental Materials, 1985
Abstract Strain in compression, compression set, stiffness and Shore A hardness of 36 brands of elastic dental impression materials have been determined. There was no correlation between compression set and the other properties tested, while statistically highly significant correlations were found between strain in compression, stiffness and Shore A ...

Universal Relations for Elastically Isotropic Elastic-Plastic Materials

Journal of Applied Mechanics, 1991
The objective of this note is to obtain universal relations for any isotropic elastic-plastic or elastic-viscoplastic materials of hyperelastic type. Using thermodynamic quantities (plastic deformation), isotropic and directional hardening, temperature, free energy, entropy, etc.

The Thermodynamics of Elastic-Plastic Materials

1991
The consequences of and the relationship among the second law of thermodynamics and the stability conditions of Il‘yushin’s type are studied. The construction of the thermodynamic potentials based on these conditions are given and the circumstances under which the potentials are unique are discussed.

Elastic modulus of trabecular bone material

Journal of Biomechanics, 1988
An ultrasonic technique was used to measure both the elastic modulus (Young's modulus) of trabecular bone material and the elastic modulus of the cancellous structure. The average trabecular modulus, measured on specimens obtained from three human and one bovine distal femora, was 13.0 GPa (S.D. 1.47) and 10.9 GPa (S.D. 1.57), respectively.

A comparison of elastic impression materials

The Journal of Prosthetic Dentistry, 1975
T ests for accuracy and other characteristics of elastic impression materials generally fall into one or more categories. These are: (1) Linear tests which measure the material itself (usually unidimensional) .le5 (2) Tests which depend upon the formation and measurement of gypsum dies made from the impression materials.
