Plate Bearing Test | CBR testing

It’s a soil in-situ load-bearing test used to determine the ground’s ultimate bearing capacity plus the possible settlement under a certain load. In a Plate Loading Test, comprehensive stress will be applied to the pavement or soil layer through rigid plates that are relatively large in size and then the deflections will be measured for different stress values.

Beam Deflection: How to Calculate - Linear Motion Tips

21/7/2016· Modulus of elasticity, also known as Young’s modulus or tensile modulus, can be defined as the ratio of stress (force per unit area) on an axis, to strain (ratio of deformation over a length) along that axis. Planar moment of inertia (also referred to as second moment of area, or area moment of inertia) defines how an area’s points are distributed with regard to an arbitrary …
