Method for determining the resistance to cracking or breaking and method for determining the resistance to shearing of elements produced from orthotropous materials, preferably from wood

摘要

the subject invention is resistance to breakage or fracture designation elements made of materials ortotropowych, which is characterized by the fact that for the test element made of material ortotropowego fixed first depth cutting, the first speed e of the thrust and the speed of the thrust.then the element is subjected to the first skrawaniu tool torque and determines the first angle cutting. then the measured power cutting during processing of the component under consideration, then, determined the first surrogate toughness.then establishes the second depth cutting, third and fourth speed speed of the thrust of the thrust, and the element is subjected to another skrawaniu rotary tool, and then measures the second power cutting during processing of the component under consideration. a second replacement toughness.on the basis of the results of both measurements removing tool for rotary, fixed value wiu0105zkou015bci for two directions ortotropowego anatomical material from which is made the test component, toughness for direction along the fibre material ortotropowego and toughness for kierunk in perpendicular to the fibre material ortotropowego.the subject invention is also designated for shear strength elements made of materials ortotropowych, especially of wood.
