비틂과 휨모멘트를 同時에 받는 均一斷面棒의 降伏條件에 관한 小考

Abstract

一般的으로, 프레임(骨組構造物)의 材料的 非線型解釋을 하는데는 降伏條件을 決定하는데 ?傷鄂? 의미가 있다.

단일한 應力상태, 예컨대 축방항력, 휨모멘트, 비틂, 전단력들중 하나만 작용할 때는 降伏條件을決定하기가 쉽지만, 특히 이들이 2개이상 組合되어 作用할때는 降伏條件을 決定하는 것이 쉽지 않다.

本 논문에서는 휨모멘트와 비틂을 동시에 받는 骨組構造物에 있어서의 降伏條件에 대해서 變形硬化를 고려하여 연구하였다.

Determination of the yield criteria generally becomes the major problems in material nonlinear analysis of the framed structures.

However determination of yield criteria under combined internal forces-axial force, bending moment, torsion, shearforce-is very difficult.

In this paper, the yield criteria of the framed structures tinder bending and twisting moment is studied considering the strain hardening effects
