Název v původním jazyce

Deformation and fracture properties of dark chocolate

Popis výsledku v původním jazyce

Series of mechanical tests (uniaxial compression test, Brasil test, plate bending test) with cylidrical specimens made from dark chocolate have been performed. The stress-strain dependence has been ploted and modeled using data from compression test. Thestrain behaviour of the chocolate was found to be far from the linear elastic strain. The linear elasticity is limited for the very small strains. The Brasil test led to the development of the tensile stress in the specimen and its cracking. The dependence of the tensile stress on the strain rate has been confirmed. Also the linearity of the force vs. displacement data received during plate bending test has been limited to the very small value of the displacemnt. Impact behaviour of the chocolate has been also evaluated. Falling of the specimen from defined hight led to its fracture. This experiment has been simulated using LS DYNA 3D finite element code.
