Structural Terms and Concepts

Front

Surface forces are caused by the direct contact of one body with the surface of another.

Back

What are surface forces?

Front

A body force is developed when one body exerts a force on another body without direct physical contact between the bodies.

Back

What is a body force?

Front

Prismatic refers to a shape where all cross sections are the same throughout its length.

Back

Define prismatic in structural terms.

Front

Homogeneous material has the same physical and mechanical properties throughout its volume.

Back

What is homogeneous material?

Front

has the same properties in all directions.

Back

What does isotropic material mean?

Front

Load factors reflect the probability that the total loading R will occur for all the events stated.

Back

What are load factors?

Front

Resistance factors (φ) are determined from the probability of material failure as it relates to the material’s quality and the consistency of its strength.

Back

What are resistance factors?

Front

Shear strain refers to the change in angle that occurs between two originally perpendicular line segments.

Back

What is shear strain?

Front

Yielding is a slight increase in stress above the elastic limit that results in a breakdown of the material and causes it to deform permanently.

Back

What is yielding in materials?

Front

The stress that causes yielding is called the yield stress or yield point (σY).

Back

What is yield stress?
