The ability to measure the mechanical properties of wood can significantly impact the efficiency, sustainability, and profitability of the wood industry. The stiffness of wood is predominantly the most useful mechanical property to be measured as it can be used for the segregation of logs into different grades. The traditional static bending test is considered the gold standard for measuring the stiffness of wood. However, this method is destructive, costly, and difficult to use. At Smart Lab we are developing Non-destructive testing (NDT) techniques to mitigate these issues.
