Real-time mechanical testing

Definition

Real-time mechanical testing refers to the evaluation of the mechanical properties of materials while they are subjected to external forces or environmental conditions. This method enables researchers to monitor changes in material behavior as they occur, providing immediate feedback and insights into performance and durability under various conditions. This approach is particularly valuable in understanding biomimetic materials, as it allows for a direct assessment of how these materials can mimic natural structures in response to dynamic loads.
