Stress–strain analysis

Stress–strain analysis (or stress analysis) is an engineering discipline covering methods to determine the stresses and strains in materials and structures subjected to forces or loads.

Stress analysis is a primary task for civil, mechanical and aerospace engineers involved in the design of structures of all sizes, such as tunnels, bridges and dams, aircraft and rocket bodies, mechanical parts, and even plastic cutlery and staples. Stress analysis is also used in the maintenance of such structures, and to investigate the causes of structural failures.
