FEA strength analyses make it possible to determine the level of stresses and strains depending on the type of loads acting on the analyzed object, the restraint method and the material parameters of the object. The information obtained allows, among other things, to specify whether the tested object has adequate strength, and whether the material used has been used in an economical way.<\/p>

STRENGTH ANALYZES OF COMPOSITE AND METAL STRUCTURES:<\/strong><\/p>

  • Analyses of the resistance of structures (aeronautical structures, windscreens and others) made of homogeneous and composite materials to impacts by foreign objects using the LS-DYNA program, including simulations of collisions with birds (ALE and SPH methods);<\/li>
  • fatigue analysis of aircraft structures, including determination of load spectra (also based on the results of operational tests);<\/li>
  • development of static and fatigue testing programs for aeronautical structures;<\/li>
  • analysis of metal structures in the field of fracture mechanics (2D and 3D) using the finite element method and the boundary element method (ANSYS 10, FRANC2D, FRANC3D, AFGROW, NASGRO programs);<\/li>
  • designing test stands with strength analysis using the finite element method;<\/li>
  • FEM strength calculations: linear statics, non-linear statics (large deformations, contact, geometric non-linearity);<\/li>
  • comprehensive research work, from the concept of the test bed, through the design and organization of the execution of the test bed elements at proven subcontractors, to the preparation of the test report.<\/li><\/ul>
