Strength Analyses


Stress/Strength analysis is an important part of engineering science, as failure of most engineering components is usually due to stress. The component under a stress investigation can vary from the legs of an integrated circuit to the legs of an offshore drilling rig, or from a submarine pressure hull to the fuselage of a jumbo jet aircraft. The purpose of the stress analyses is to investigate the structure's response and the stress distribution due to the internal or external static loading. Modelling the boundary conditions along with finite element mesh distribution in important to represents the reality.

VES provides services often complex in nature complex which included
  • Linear – elastic static stress analyses
  • Stress analysis with Non –Linear contacts with structures (e.g. bolted connections, mounting contact surface)
  • Stress analysis with non –Linear materials. (Taking into account effects such as plasticity, visco-elasticity, hyper-elasticity)
  • Stress analysis with geometric non-linearity (large deflections)
Domain Expertise/Application areas
  • Offshore Structures (including ships, platforms, Barges, Floating Decks, Carnes)
  • Industrial Equipment (including turbines, compressors, High pressure storage tanks, Pumps, Valves, AC plants, pressure vessels)
  • Automotive Components (including Piston, Crankshaft, chassis, suspension) Although the fundamental principals are the same, offshore and land structures differ in perspective of variety of analyses and loads. Both offshore and onshore structure analyses are in field of our interest and we provide services for both civil and military purposed branches of industry such as
Land Structures
  • Iron Concrete or Steel Buildings
  • Bridges
  • Industrial Facilities
  • Pressure Vessels
  • Machinery and Machinery Parts
  • Vehicles and Vehicle Parts
Offshore Structures
  • Platforms
  • Barges
  • Floating Decks
  • Floating Cranes
  • Ships

Vibration Analysis


Every object in the nature has endless number of vibration frequencies and mode shapes that are called "Natural Frequencies". Calculation of these frequencies and their mode shapes are important to solve the vibration induced engineering problems. Natural frequencies and mode shapes of simple objects can be found by using analytical methods. However, complex shaped objects can only be analyzed by numerical methods. Finite element methods and the improved computer calculation capacities enable to investigate the natural frequencies and mode shapes of complex structures by idealizing them into computable small parts which are called "finite elements".

Structural analyses can be summarzied into the following types;
  • Crash Test Analyses
  • Thermal Analyses
  • Mechanism Simulation Analyses
  • Vibration Analyses
  • Dynamic & shocks analyses
  • Fatigue Analyses
  • Strength Analyses
Vibration analyses can be divided into two main parts. These are;
  • Natural frequency and mode shape extraction
  • Forced vibration analysis
