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 mechanical engineers involved in the design of structures and equipment of all sizes, such as buildings, cranes, aircraft and rocket bodies, mechanical parts, and even plastic cutlery and staples. Stress analysis is also used in the maintenance of such, and to investigate the causes of structural failures.
Typically, the input data for stress analysis are a geometrical description of the structure or equipment, the properties of the materials used for its parts, how the parts are joined, and the maximum or typical forces that are expected to be applied to each point. The output data is typically a quantitative description of the stress over all those parts and joints, and the deformation caused by those stresses. The analysis may consider forces that vary with time, such as engine vibrations or the load of moving vehicles. In that case, the stresses and deformations will also be functions of time and space.
In engineering, stress analysis is often a tool rather than a goal in itself; the ultimate goal being the design of structures and equipment that can withstand a specified load, using the minimum amount of material or satisfying some other criteria.
North West Projects perform stress analysis on different structures and components using both analytic mathematical modelling (MathCAD), and computational simulation (FEA). The FEA is carried out using the following software packages:
- STAAD Pro
- CAESAR II
North West Projects has the experience and the capability of performing linear, non-linear, static, seismic and transient analyses. Relevant code compliance checks are carried out on all analysis work undertaken.
