Abstract. Oranges and grapefruit were subjected to single and repeated impact drops from three heights. Subsequent measurements of the force‐deformation ratio and hysteresis loss were made with quasi‐static compression tests on the impacted whole fruit. Internal damage was indicated by a reduction in the force‐deformation ratio and an increase in the hysteresis loss for a single 100 cm drop and two or more drops from 25 or 50 cm he
