Experimental study on mechanical properties of reed stalk

Abstract

Abstract Reed is a kind of important natural resources. The inherent mechanical properties of reed stalk are the basis for development of its production equipment. As the research on the basic mechanical properties of reed stalk is still in blank both at home and abroad, this paper makes the compression, tensile, and bending experiments respectively on the bottom reed stalk in the harvest time with an electronic universal testing machine, obtains the corresponding stress-strain curves under the compression, tensile, and bending loads, and confirms that the mean compression strength is 2.69 MPa, the mean compression elasticity modulus is 75.52 MPa, the mean tensile strength is 16.45 MPa, the tensile elasticity modulus is 433.19 MPa, the mean bending strength is 2.15 MPa, and the mean fracture deflection is 5.54 mm. The experimental results may provide a reference for the development and parameter optimization of the reed production equipment.
