为了研究3D打印钛合金缺口件局部循环塑性行为,首先,通过有限元法对缺口附近局部应力与应变场进行详细的分析,深入了解应力和应变场的演变,分析成型方向对结果的影响;其次,开展试验研究并针对成型方向对结果的影响进行分析。结果表明,缺口根部发生棘轮变形,L
3
方向的棘轮应变率最大,L
1
方向的棘轮应变率最小。成型方向对应力三轴度影响并不太明显,并且不同成型方向的弹性应变能几乎没有差别,但成型方向对塑性应变能影响很大。随着循环次数的增加,不同缺口半径的塑性应变能结果差别也越来越大。
The main purpose was to study the local cyclic plastic behavior of 3D printed titanium alloy notched parts. Firstly
the local stress and strain field near the 3D printed titanium alloy notch was analyzed in detail by finite element method, and the evolution of stress and strain field was deeply investigated. Then
the experimental study was carried out and the influence of the forming direction on the results was analyzed. The results show that ratcheting deformation occurs at the notch root
with the maximum ratcheting strain rate in the L
3
direction and the minimum ratcheting strain rate in the L
1
direction. The influence of the forming direction on the stress triaxiality is not too obvious. The elastic strain energy of different forming directions is almost no difference. However
the forming direction has a great influence on the plastic strain energy. With the increase of the number of cycles
the difference of plastic strain energy results for different notch radii also becomes larger.
