STRUCTURES

Types: Massive Structures Frame Structures Shell Structures

STRUCTURES Massive Structures

They are made of solid material, filling the body completely

STRUCTURES Frame Structures

They are composed of long elements (bars, tubes,...) joined to each other at the ends

STRUCTURES Shell Structures

They are made of a thin outer layer of material that surrounds a volume

STRUCTURES

Forces acting on a Structure: Tension Compression Bending Torsion Shear

STRUCTURES

Tension vs Compression

Tension: it is composed by two opposite aligned parallel forces which try to separate the particles of the material.

Compression: It is composed by two opposite parallel forces which try to join the particles of the material.

STRUCTURES

Bending vs Torsion

STRUCTURESBending vs Torsion

Bending: In bending effort,the forces try to bend the object

Torsion: The forces try to twist the object

STRUCTURES

Shear Forces

Shear: Two forces try to cut the Object.
