Modeling the earth's fluid and elastic response to the melting of the glaciers of the last ice age is the most direct way to infer the earth's radial viscosity profile. Here, we compare two methods for calculating the viscoelastic response to surface

Seven simply supported steel beams were built and tested to provide a better understanding of how prestressed strands affect the steel beams’ behavior during the yielding stage. Steel beams had identical clear span lengths (2.85 m) and gross-sectio

Shrinkage and improper compaction of the repair layer are among the main reasons for the adhesion drop. Shrinkage results in cracking and improper compaction causes fine pores in the interface. Due to the fact that shrinkage and non-compacting are th
