Abstract: A new and accurate formulation of the stiffness matrix for an axisymmetric interface or joint element is presented. This element is formulated to model rock joints and soil-soil and soil-structure interfaces in the finite ...

Abstract: Pavement distress information is important to highway engineers in managing pavement networks. At the present time, there are several research groups working to develop a more efficient and unbiased method of obtaining ...

Abstract: Robotic missions to Mars are listed and significant results of each past mission related to soil engineering are noted. What is known of the Mars environment and surface features that may be of interest to the engineer is ...

Abstract: How do we begin to expand our civilization to the Moon? What are the technical issues that infrastructural engineers, in particular, must address? This paper has the goal of introducing this fascinating area of structural ...

Abstract: A viscoelastic solution for a pipe buried in a homogeneous and isotropic soil is presented. The linear viscoelastic solution is obtained by transforming Hoeg's elastic solution using the (correspondence principle.) To ...

Abstract: Knowledge of the lunar regolith is essential to success in lunar missions whether crewed or robotic. The regolith is the loose material overlying more intact strata on the Moon. It varies in ...

Abstract: Lunar-based astronomy requires structures that provide the required stiffness, strength, and dimensional stability in the challenging lunar vacuum, thermal, radiation, micrometeorite, secondary ejecta, ...

Abstract: A telescope on the Moon is needed for astronomy and can be constructed in this decade or early in the next century. Design for this telescope will be fundamentally different from the design of free‐flying telescopes. Its ...

Abstract: The best location in the inner solar system for the grand observatories of the 21st century may be the Moon. A multidisciplinary team including university students and faculty in engineering, astronomy, physics, and geology, ...
