The paper deals with a finite element modelling of implants in the problem of ventral hernia repair. The synthetic mesh implanted in the abdomen during surgery is here modelled as a membrane structure. Thesystem undergoes the internal abdominal pressure that occurs during the postoperative cough, the load identified in the literature as the main cause of the connection failure and hernia recurrence. The model can be used to estimate the forces appearing in the connections of tissue and implant for different materials of implants and different number of tacks. This can help to predict the fixing system, such as the number of tacks etc. to be provided during the surgery in order to resist the cough pressure and avoid the hernia recurrence. Thedynamic analysis of the structure is compared to the laboratory experiments in a pressure chamber to demonstrate the accuracy of the proposed model.
