### Strength and Stiffness Problem Solving

The objectives of the static strength and stiffness are

• static analysis
• buckling analysis Static analysis allows the calculation of the stress-strain state of the structures under the action of loads applied to the system. Today, this is perhaps the most popular in the design task. The calculation allows us to estimate the strength of the developed structure of allowable stresses, determine the most weaknesses in the design and make necessary changes (optimize) the product.

Static analysis also allows

• take into account the geometric nonlinearity
• to take into account non-linear material properties, as well as the anisotropy of properties
• to determine the stress-strain state of the effects of temperature
• perform calculations of contact problems Static analysis allows to solve problems fracture mechanics associated with determining the position of a possible occurrence of cracks and appearance design of the plastic hinge.

The main results of static calculations are as follows:

• displacement field in the design reference points finite element mesh
• strain field
• field stress components
• strain energy
• nodal force
• safety factor field distribution

These data are usually sufficient to predict the behavior of structures and decision-making to optimize the geometric shape of the product. Buckling analysis important when designing structures, operation of which involves exposure to compressive loads. This analysis allows us to estimate the safety factor for the so-called. "Critical load" - load at which the design can be significant leaps inelastic deformation, often leading to its destruction or serious damage, as a consequence of the loss of a stable form of equilibrium.

As a result determine the value of the critical load factors for which there is a loss of stability, and the corresponding buckling.
