ANALYSIS SERVICES

Structural analyses are divided as static and dynamic. Static analysis is the most basic and common type of analysis and is used to obtain the strength of structures under time-independent loads.

In dynamic analysis, loading conditions change as a function of time, and inertia and damping play an important role in the behavior of the structure. As a general rule, dynamic analysis should be done if the frequency of load is higher than 1/3 of the lowest natural frequency of the structure.

Explicit finite element analysis; is used in situations where extreme shape change occurs at very short intervals of time. It is widely used especially in production simulations, automotive, and Defense & Aerospace sectors. Analyses such as vehicle crash, sheet metal forming, and blast effect on the structures are typical examples.

There are four types of vibration analysis; Modal, Harmonic, Spectrum and Random Vibration.

Modal analysis is used to find the natural frequencies and mode shapes of the structure.

Harmonic analysis provides behavior in the form of steady state harmonic loads.

In spectrum analysis, it is used to find the response given by earthquake loads.

Random vibration analysis is used to investigate the behavior of structures on the basis of random vibrations.

Structures subjected to repetitive loading may not exhibit any damage occurrence at the beginning, however at certain number of cycles they fail due to fatigue.

Fatigue analysis is used to determine at which loads and cycles can be safely restrained under repetitive loads.

There are three basic methods of fatigue analysis.

  • Stress Life
  • Strain Life
  • Fracture Mechanics

Multi Body Dynamics (MBD) is a simulation of the forces and moments that occur in rigid/elastic parts connected to a body. Different mechanisms such as automobile suspension, aircraft landing gear and wing flaps can be simulated with MBD. In MBD method, the elasticity of parts in critical situations can be included in the simulation of the mechanism.

Thermal analysis by finite element method is generally used to find the distribution of temperature and heat flow in the components and assemblies with complicated shapes due to the three basic heat transfer way, conduction, convection and radiation.

Analyses are referred to as `linear` if the thermal properties are constant, and `non-linear` if they are variable.

If thermal loads are time independent; they are called `steady state`, if not `transient`.

Computational Fluid Dynamics (CFD) is a method to find the behavior of fluids in complex geometries and boundary conditions using numerical analysis. The problems of any kind of pipeline flow, aerodynamic flows, flows in ventilation systems, fluid and structure interaction (FSI) can be solved by CFD.

The main purpose of hydrodynamic analysis is the simulation of movements of floating structures at sea states. It is also necessary to have the following loads for the structural analysis to be carried out in the future.

Inertial loads due to the acceleration of the floating structure.

Pressure load on the ship's hull and compartment walls.

Loads to mooring lines and risers.

Composites materials are intended to be used more extensively as an alternative of aluminum structure in automotive, aerospace and defense applications. This is due to their attractive properties as high strength-to-weight ratio and stiffness-to-weight ratio. Finite element analysis for composite materials enable engineers and analysts to simulate a wide variety of composite materials used for complex components and assess their design scenarios confidently.

FEM Simulation of Additive Manufacturing eliminates the guesswork and hours of wasted time in metal additive manufacturing (AM) workflows. This solution is essential for AM operators and designers that need to build parts first-time-right. Our team has extensive knowledge on simulation as well as testing of composites and additive manufacturing processes is ready to help you to solve your design problems in these fields.
