Mechanical problems of superplastic fill-forming bulge solved by one-dimensional tensile and two-dim
[期刊论文] 作者:SONG Yuquan,LIU Shumei,
来源:自然科学进展 年份:2004
Because of the strong structural sensitivity of superplasticity, the deformation rule must be affected by stress-state. It is necessary to prove whether one-dim...
