Study on the hardness of curved rebar by a simple bending machine
Get PDF異形棒鋼は用途に応じて曲げ加工されて利用される．異形棒鋼の曲げられた部分の材料特性は加工硬化により変化する．土木工事などでは，曲げられた部分をさらに曲げ加工することがあるため，材料特性の変化を把握することは重要である．本研究の目的は，加工による材料特性の変化を把握する第一歩として，曲げ加工後の異形棒鋼の硬さ分布を明らかにすることである．本研究では，3種類の回転角度で加工した異形棒鋼を4つの領域に分けて硬さ試験を行った．支点ローラに押し付けられて曲げられる領域は，回転角度が増加しても硬さはあまり変化しない．棒鋼受けと支点ローラの間ならびに支点ローラと力点ローラの間の領域は，支点ローラに近いほど硬さの測定値が大きい．Rebars are used by bending according to the purpose. The material properties of bent portion of rebars change due to work hardening. In civil engineering work, it is important to understand the changes in material properties because bent portion are sometimes further bent. The purpose of this research was to clarify the hardness distribution of a rebar after bending as a first step in understanding the changes in material properties due to processing. In this research, rebars bent at three different rotation angles were divided into four areas for hardness test. The area that is pressed against the fulcrum roller and bent does not change much in hardness as the rotation angle increases. In the area between the rebar receiver and the fulcrum roller and between the fulcrum roller and the circular roller, the closer to the fulcrum roller, the greater the hardness measurement.application/pdfdepartmental bulletin pape
Analysis of Uniform-Strength Shape by the Growth-Strain Method (Application to the Problems of Steady-State Vibration)
Get PDFThe growth-strain method, developed using the finite-element calculation of the deforming of shapes produced by swelling and contracting of itself, was previously proposed as a shape optimization method. The present report describes an application of the growth-strain method to the problems of steady-state vibration. In particular, free vibration with a normal mode and vibrational response to a harmonic excitation are considered. A difference of the implementation of the method for these vibration problems from that for static problems lies in analyzing the stress distribution at the deformation in the normal mode or in the amplitude of the vibrational response. Numerical examinations are carried out on simple beam structures. In these examinations, the growth-strain method shows a feasibility even in the optimization of structures under dynamic circumstances.journal articl
