New simplified formulas for ELF subsurface-to-subsurface propagation

A new plan to connect aluminum tubes of subsurface structures

  In this study, a new method for joining aluminum tubes in subsurface structures using steel converting and aluminum welding are presented and reviewed. But near the weld area is under high thermal cycle and will cause residual stresses in heat affected zone. Therefore for assessment of proposed connection from the perspective of residual stress by using the finite element method welding of tu...

Subsurface Science

TanGeoMS for visualization of subsurface

Understanding subsurface conditions like soils properties or geological stratification is hindered by the lack of measured data as well as by the unavailability of models, tools and visualization techniques addressing the complexity of subsurface data. The intrinsic three-dimensionality of the subsurface is often simplified into two dimensions; looking either at the spatial component using stan...
