Caracterização mecânica de elementos de compensado naval

Abstract

Wood has been proving itself as a low environmental impact and versatility alternative in use in recent years. In addition, innovative forms of industrialization of wood should be developed, as should advances in forestry engineering techniques and changes in legislation related to their exploitation and marketing. In view of this and the possibility of application in digital manufacturing, the Casa Nordeste Project produces a compact housing model whose base material of the structure is naval compensated. For the use of this type of plywood in the project, it was necessary to obtain mechanical properties of the material, such as the modulus of elasticity and flexural strength, as well as the analysis of these values in elements with real and reduced scales. The results for the modulus of elasticity in the longitudinal and transverse directions and flexural strength in the longitudinal and transverse directions were, respectively, 3359.98 MPa, 2061.59 MPa, 29.33 MPa and 25.66 MPa. In addition, the influence of the lateral torsional buckling effects on the tested elements was verified, confirming that the phenomenon is related to the slenderness of the studied element, as well as analyzing how the shear effects influence the action deflection field.
