Mechanical properties of building materials

The mechanical properties of materials refer to the deformation and resistance of materials under external forces.


1. strength


Strength of materials


Strength grade


Specific intensity


2. deformation properties of materials


Elasticity and plasticity


Elasticity: the material under the action of external forces to produce deformation, when the removal of external forces, deformation can be fully restored to the property known as the elasticity of materials.


Plasticity: the material under the action of external forces produced by the deformation, after the removal of external forces, the material remains after deformation shape and size properties, known as the plasticity of materials.


Brittleness and toughness


Brittleness: The property of a material that fails suddenly without significant deformation under external forces. Material with this property is called brittle material.


Toughness: Under impact and vibration loads, materials can withstand large deformation without sudden failure. Materials with this property are called ductile materials.


3. durability of materials [1]
