Finite Element Analysis of Mechanical Damage in Horticultural Produce
Summary
Finite element analysis (FEA) has emerged as a pivotal tool for understanding and mitigating mechanical damage in fruits and vegetables. By constructing three-dimensional computational models that replicate the complex geometry and layered structure of horticultural produce, researchers can simulate impact, compression and vibration events that occur during harvesting, transport and storage. Experimental measurements of tissue mechanical properties—obtained through indentation tests, pressure sensors or imaging-based deformation studies—are used to calibrate viscoelastic and elastic–plastic constitutive models. High-resolution meshes capture variations in skin thickness, flesh firmness and core stiffness, enabling prediction of bruise initiation, propagation and final volume under varying loading scenarios. Such simulations guide the design of cushioning materials, packaging systems and handling protocols, with a view to reducing post-harvest losses and maintaining quality throughout global supply chains.
