Mechanics of materials

What are we studying in mechanic of materials?

• The properties of materials and how they response to loads.

• The relation between internal and external loads applied to a body and how this loads can impact in its deformation and stability.

• The behavior of materials properties when a normal or shear stress is applied.

What is the difference between statics and mechanics of materials?

• Mechanics of materials takes into account that a body deforms when a load is applied while statics just considers an undeformed body.

• Statics calculates forces and moments and mechanics of materials considers stress calculation.

• Mechanics of materiel considers the properties of solid bodies which suffer a deformation due to various types of loading and statics considers the forces and moments which a rigid body suffers.

Force applied parallel to the surface of and object

• Tensile

• Torsion

• Shear

Force applied perpendicular to the surface of and object

• Compression

• Flexion

• Shear

What are the assumptions in mechanics of materials?

• Body is homogeneous, isotropic, elastic and prismatic

• Body is homogeneous, anisotropic, elastic and prismatic

• Body is homogeneous, polytropic, elastic and prismatic.
