Length(35 foot) x Width(11 foot) x Depth(4inches/12 foot) = volume(128.33 cubic foot) Volume(128.33 cubic foot) x Density(45 pounds/cubic foot) = Weight(5774.85 pounds)

2016-9-21 · The P-α equation of state is designed for modeling the compaction of ductile porous materials. The implementation in Abaqus/Explicit is based on the model proposed by Hermann (1968) and Carroll and Holt (1972). The constitutive model provides a detailed description of the irreversible compaction behavior at low stresses and predicts the correct thermodynamic …

So, drainage density is the most triggering factor for landslide in Sikkim Himalaya. The less permeable rock is, the less the infiltration of rainfall, which conversely tends to be concentrated in surface runoff. The drainage density of the study area is calculated using the line density analysis tool in Arc GIS 10.4 software.
