摘要

摘要对苹果品种锦葵（Malus domestica L.）在横向压缩载荷下的试验和数值评价进行了研究。在两个平行的平板之间观察了果实半球行为的发展。苹果样品在不同的应变率下进行测试。为了获得不同的应变速率，实验在10至350 mm·min−1的11个速度下进行。果实在不同应变速率下的压缩试验对应于准状态载荷。研究了加载速率和应变速率对压缩力和应力的影响。该材料表现出应力对应变的非线性依赖性，而应力对应变速率的线性粘弹性依赖性。评价了Kelvin-Voight粘弹性模型的应用可能性。为了检测不同应变速率下的果实损伤，评估了力、应变、应力和表观弹性模量。

Compressive Loading of Apple Cultivar Golden Delicious

Abstract The study dealt with the experimental and numerical assessment of the apple cultivar Golden Delicious (Malus domestica L.) at compressive loading in lateral direction. The development of fruit hemisphere behaviour was examined between two parallel plates. Apple samples were subjected to tests at different strain rates. The experiments were conducted at eleven velocities from 10 to 350 mm·min−1 for the purposes of achieving different strain rates. Compression tests of the fruits at different strain rates corresponded to the quasi-state loading. Impacts of loading rate and strain rate on force and stress at compression were studied. The material exhibited nonlinear behaviour of dependency of stresses on strains, but linear viscoelastic behaviour of dependency of stresses on strain rate. The application possibilities of Kelvin-Voight viscoelastic model were evaluated. Forces, strains, stresses and the apparent moduli of elasticity were evaluated for the detection of fruit damage at different strain rates.
