The behavior of cement-bonded wood-chip material under static and impact load
Original language description
The response of cement-bonded wood-chip (CBWC) material under static and dynamic load was investigated both experimentally and numerically. This investigation is a part of complex development of safety road barrier with integrated noise protecting wall based on the wood-chip boards. Three types of materials with different amount of the binder were investigated in two moisture content states in order to obtain a comprehensive overview of the properties and behavior of the material at several types of loading, necessary for future design of the safety barrier. Real quasi-static (compressive, tensile and flexural strength) and dynamic experiments (IZOD test and Newton Cradle drop test) were carried out. The research revealed strong dependence of the mechanical properties on the moisture content in the material, with different trend – toughness showed ascending trend with increasing moisture content, whereas compressive, flexural and tensile strength were lower when the CBWS material was soaked. The results of the tests were used as inputs for creating and subsequently verifying the numerical material model of cement-bonded wood-chip material. The material model was used in numerical simulations of crash test of mobile noise protecting wall according to the ČSN EN 1317 standard.
