Hydrostatic creep tests were run on cylindrical specimens of Rome Beauty apples to study the mechanical response. Volumetric strain was measured for different levels and durations of applied stress. The former was separated into recoverable, permanent, instantaneous, and time dependent components. A general constitntive relationship was developed from statistical analysis. A mechanical model was proposed to explain the strain response of the material.
