CIVL 2020 Lab No. 2 Steel and Timber in Shear

These flashcards encompass key vocabulary and concepts from the CIVL 2020 Lab on Steel and Timber in Shear, aimed at aiding study and retention for exam preparation.

Ultimate Shear Strength

The maximum shear stress that a material can withstand before failure.

Longitudinal Shear Strength

The resistance of a material to shear forces acting parallel to the grain.

Average Shear Stress

The shear force acting on a section divided by the cross-sectional area.

Unit Shear Stress

Shear stress calculated on a unit basis, often used in the analysis of timber.

Anisotropic Material

A material with different properties in different directions, like timber.

Isotropic Material

A material with uniform properties in all directions, such as steel.

Lignin

A glue-like substance in wood that binds cell walls together.

Single Shear

A shear test condition where the load is applied to a specimen supported on one side.

Double Shear

A shear test condition where the load is applied to a specimen supported on both sides.

Ductile Material

A material that can undergo significant plastic deformation before fracture.

Transverse Shear Stress

Shear stress that occurs across the cross-section of a material due to loading.

Safety Factor

A design criterion that provides a margin of safety in structural design, calculated by dividing the material strength by the actual applied load.

Failure Mode

The manner in which a material fails under stress, which can be sudden or gradual.
