Adjustments of dynamic MoE on referent moisture content of wood and temperature in grading of small-sized samples

Adjustments of dynamic MoE on referent moisture content of wood and temperature in grading of small-sized samples

Mathematical dependences are derived for non-destructive testing (NDT) and destructive testing (DT) of three timber sets, each with six beams made of soft and hard structural timber. Very strong correlations were established between elastic moduli (e-moduli) determined by non-destructive testing, fr...
