Geosynthetic-reinforced soils above voids: Observation and prediction of soil arching
(
Elsevier
, 2021 , Article)
The assumption with the biggest impact on the design of geosynthetic-reinforced soils above voids is the presence and degree of soil arching, which affects the predicted applied stress on the geosynthetic. A series of ...
In-plane stress analysis of multiple parallel cracks in an orthotropic FGM medium under time-harmonic loading
(
Elsevier
, 2021 , Article)
This study aimed to investigate the fracture behavior of a cracked orthotropic FGM medium when exposed to an in-plane harmonic load. The mechanical feature of the medium exponentially varied along the y-axis. Using the ...
