Session 2 - Round table “Measuring More to Understand Less?”

This special round table, initiated and coordinated by the CNRS GDR Mecabio and the Euromech 670 Organising Committee, aims to stimulate a collective reflection on current practices in soft tissue biomechanics among all colloquium participants.

Soft tissue mechanics is increasingly characterised by highly sophisticated experiments and ever more complex constitutive models. Yet, fundamental questions remain: Why do we build increasingly complex models when available data remain limited? Do we actually gain clarity or just more parameters? How far should we seek identifiable parameters and minimised uncertainty? Is a model truly validated if only specific quantities are predicted correctly?
Structured as a dynamic and interactive discussion, this session will explore central themes including:

  • Model complexity versus scientific necessity
  • The quest for identifiability versus physical realism
  • Validation and the true scientific value of our models

Rather than seeking a simple consensus, the goal is to expose underlying assumptions, clarify methodological tensions, and encourage constructive debate across communities. This round table aims to create a space where experimentalists, theorists, and modellers can openly challenge each other’s perspectives and collectively discuss how we measure, model, and interpret soft tissue mechanics.
