Dimension reduction for elastoplastic rods and homogenization of elastoplastic lattices

open access: yes, 2021
We derive effective equations for periodic lattices of linearly elastoplastic rods in the limit of both infinitesimal periodicity and infinitesimal relative width of the rods. For this derivation we use the method of evolutionary Γ-convergence for quadratic rate-independent systems.

Research and application of high temperature low-density elastoplasticity cement slurry

open access: yesYouqicang pingjia yu kaifa, 2020
In Ordovician of Tahe Oilfield, the bottom hole temperature is high, the seam hole is developed, the leakage easily occurs, and the annular clearance of cementing is small. Therefore, the conventional low density cement slurry system cannot guarantee the
