What does undrained shear strength mean?

The undrained shear strength (su) is defined as the peak value of the horizontal shear stress. The undrained shear strength Csul is defined as the peak value of the horizontal shear stress.

What is residual shear strength?

The residual shear strength is the centre of focus of many researchers for slope stability analyses of old landfills where a slip surface exists. A residual shear strength of clayey soil is defined as the minimum shear strength of the soil along an existing shear surface.

What is remolded soil?

[rē′mōl·dəd ′sȯil] (geology) Soil that has had its natural internal structure modified or disturbed by manipulation so that it lacks shear strength and gains compressibility.

What’s the difference between undrained and remoulded shear strength?

Your reported undrained shear strength is low but not uncommon. The remolded shear strength is related to the Sensitivity of your clay…sensitivity is the ratio of the undisturbed shear strength to the remolded shear strength.

Which is the best definition of shear strength?

shear strength. The resistance of a material to force applied perpendicular to the plane of the material.

How is shear strength related to sliding failure?

Shear strength is a material property that describes a material’s resistance against a shear load before the component fails in shear. The shear action or sliding failure described by shear strength occurs parallel to the direction of the force acting on a plane.

Why is shear strength important for ductile materials?

In order to understand shear strength, understanding different theories of failure are important. Generally for brittle materials, the cause of failure is due to a force in tension. For ductile materials, the cause of failure is often due to shearing forces. The stress-strain curve for these two types of material is different.
