Finite element method application for modelling of internal oesophageal prosthesis

Purpose: The general topic of this paper is the computer simulation with the use of finite element method for determining the internal stresses in the internal oesophageal prosthesis based on long-fibre composite material. Design/methodology/approach: Modelling of stresses in the internal oesophageal prosthesis was performed with the help of finite element method in ANSYS environment. Application of Finite Element Method was discussed and essential advantages resulting from application of it are pointed Findings: The presented model meets the initial criteria, which gives ground to the assumption about its usability for determining the stresses in the internal oesophageal prosthesis, employing the finite element method using the ANSYS program. The computer simulation results correlate with the experimental results. Research limitations/implications: Applied Finite Element Method enables modelling of stresses and deformations arises in composite material in the conditions representing real experimental investigations as well as condition similar to those prevailing in human body after prosthesis implementation. Originality/value: Developed simulation simplifies and reduces cost of optimization of the internal oesophageal prosthesis properties by simulation of this properties without necessity of additional laboratory investigations.
