Method & Evidence

AimHow can simulation models, validated by experimental data, be used to optimize the geometric parameters of bio-inspired suture structures to enhance their flexural properties?

MethodExperimental and Numerical Simulation

ProcedureBio-inspired suture structures were fabricated using multi-material additive manufacturing. Print quality and interfacial hardness were assessed. Flexural properties were tested by varying soft layer thickness and suture module sizes. A numerical simulation model was developed and validated against experimental results. A Design of Experiments (DoE) approach was then employed within the simulation to analyze the effect of changing suture geometry on performance.
