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.
