  • ESAComp can be used for designing straight and conical composite tubes with a circular cross section. The performance of the structure can be studied under various condition.
  • ESAComp provides an extensive data bank for commercial material grades. Laminate designs can be based on the readily available materials or the user can define his/her own material systems.
  • In ESAComp, the model creation is easy and fast. The engineering effort can be directed to laminate design rather than finite element modeling.
  • The benchmark study [1] involves the stability analysis of an axially loaded thin-walled composite cylinder. The linear static analysis results of ESAComp correlate very well with the published data.
