High-temperature mechanical, physical and Thermal properties of granitic rocks— A review
TL;DR: An extensive literature review was performed to assemble data on the following properties: modulus, Poisson's ratio, tensile strength, compressive strength, viscosity, thermal expansion, density, permeability, melting temperature, heat of fusion, specific heat, thermal conductivity and thermal diffusivity.

Thermal stress cracking in granite
TL;DR: In this article, the authors count acoustic emissions and measure compressional wave velocities while a sample is heated to a maximum temperature of 300°C under confining pressures up to 55 MPa.

The plume head–continental lithosphere interaction using a tectonically realistic formulation for the lithosphere
TL;DR: In this article, a tectonically realistic continental plate model is proposed for large-scale plume-lithosphere interaction, which includes a natural free surface boundary condition, an explicit elastic-viscous(ductile)−plastic(brittle) rheology and a stratified structure of continental lithosphere.
Journal ArticleDOI
The influence of microcrack density on the elastic and fracture mechanical properties of Stripa granite
TL;DR: In this paper, the density of microcracks in the heated rock is studied by means of optical microscopy, SEM and differential strain analysis (DSA), which reveals a large increase in microcracking when the heat treatment temperature exceeds 300°C.

Physical properties of shale at temperature and pressure
TL;DR: In this article, the authors measured deformation properties of three North Sea Malm shales in the laboratory under pressures to 800 bars and temperatures to 100 degrees C. The deformation in the shales is dominated by inelastic processes which cause time-dependent changes in velocity, resistivity, and pore pressure.

Single Crystal Elastic Constants and Calculated Aggregate Properties. A Handbook
Gene Simmons,Herbert F. Wang +1 more
TL;DR: In this paper, the authors present data on the elastic properties of single crystals collected from the literature through mid-1970 and the elastic property of isotropic aggregates which are calculated according to the schemes of Voigt and Reuss for all materials, and Hashin and Shtrikman for materials with cubic symmetry.

Single crystal elastic constants and calculated aggregate properties
TL;DR: In this article, the elastic properties of isotropic aggregates (Young's modulus, Poisson's ratio, shear modulus and bulk modulus) are calculated according to the schemes of Voigt and Reuss.

Thermal expansion behavior of igneous rocks
Dorothy Richter,Gene Simmons +1 more
TL;DR: In this paper, the authors show that the observed thermal expansion is a function of crack porosity, heating rate, and previous maximum temperature as well as mineralogical composition and preferred crystal orientation.
