... ABSTRACT Successful location of icy deposits on the moon and other planets requires detailed knowledge of the physical properties of both icy and ice-free potential reservoir materials in order to design geophysical equipment, implement surveys, and interpret data. In support of this goal, we...

... and buildings. These rocks can be naturally or anthropically exposed to high temperatures. Consequently, relating their physical properties to temperature induced damage becomes extremely important. Key physical and mechanical properties, such as porosity, seismic wave velocities, electrical resistivity...

... and focus efforts on areas most in need of improvement. More importantly, this new discipline would naturally take on the role of building image-based predictive petrophysical and geomechanical models by leveraging many decades of research on the microstructural control of physical properties. Such image...

... based on MPS. MPS analyzes the part of fluid alone and DDA analyzes the part of solid alone to set the initial state of the analysis. After the results is superimposed, the coupling analysis is carried out. 1. INTRODUCTION coupling analysis physical property debris flow discontinuous...

... extraction or deep underground mining engineering. The temperature changes lead to the changes in stress field and may induce microcracking. The temperature and stress field variation together with possible microcracking also influence the mechanical and physical properties of rock itself. From...

... compressive strength tests. The results obtained before and after cycling were compared and used to calculate the weakening coefficient, defined as the relation between the uniaxial compressive strength after cycling divided by the result obtained on natural rock samples. The major physical properties...

... ABSTRACT Natural stones shall be classified related with their qualities. The quality of the natural stones can be determined by quantifying the mechanical and physical properties from experiments. Texture of natural stones also carries important clues regarding the quality of materials...

High tensile strength...

... and physical properties. Core specimens of Ocala limestone with varying weathering states were tested to determine relationships between physical and index properties. Each weathering state was associated with either two or three hardness values and as weathering state increased hardness decreased. Results...

... and 100% saturated samples. Water-saturation treatment was done prior to the instantaneous freezing, which is achieved by submerging samples in liquid nitrogen. Physical properties of the granite such as density, wave velocity and Young?s Modulus were observed to be decrease at bone-dry and saturated...

.... Material properties, for the purposes of this discussion, are considered the physical properties or characteristics of the regolith and/or rock which will affect its excavatability of a material. These properties will determine the cutting forces for a given penetration, and the energy required to remove...

... ABSTRACT: SALTDATA is a database, for the physical properties of those rocks commonly associated with the mining of salt and potash, written for the relational database Paradox 3.0. The application is structured as a series of tables and runs on IBM-PC compatible computers operating under MS...

... ABSTRACT INTRODUCTION The upper part of the earth's crust is highly fractured on all scales ranging from microcracks to large-scale joints and faults. Joints are well known for their effects on the physical properties of a rock mass. Mechanical properties such as bulk elastic constants...
