Instructions for the second international benchmarking exercise on longitudinal tensile failure are now available!
Several models for predicting the tensile response of unidirectional composites are available in the literature. Each of these models is based on a unique set of assumptions, and formulations vary significantly across the different models. The idea of this exercise is to compare the predictions of different models, not only with each other but also with experimental data. This comparison will focus on the tensile strength and accumulation of fibre damage in unidirectional composites.
1. To establish benefits and drawbacks of the different approaches.
2. To establish gaps in literature and aspects that should be improved in the future.
3. To provide a platform for researchers in this field to exchange thoughts and concerns.
In the long term, and depending on the outcome of the benchmarking exercise, the goal would be to further develop the models and move towards more practical and complex applications.

Official announcement of the second version of benchmarking exercise for longitudinal strength models of UD composites
The second version of the benchmarking exercise has now opened. We welcome participation from groups all over the world to contribute modelling predictions to this exercise.
Let us stop the hypocrisy of nicely matching experimental validations
Experimental validations are vital to any model development. This is also why it ended up to be a key component of the FiBreMoD project. For a long time, I have felt that models for composite failure have been insufficiently validated by experiments. I believe this has several reasons:
