本研究针对钛板材成形中回弹 (springback)和厚度不均的行业难题，通过1-100 mm/min梯度速度的V型弯曲实验，结合EBSD (电子背散射衍射)和KAM (核平均取向差)分析，首次揭示了高速弯曲会形成厚中层弹性区加剧回弹 (7.0° vs 5.8°)，但能提升厚度均匀性 (Δt 降低50%)的竞争机制，为航空航天领域高精度钛构件 ...

Springback in sheet metal forming is becoming a very troublesome issue with the increased use of high strength steels in automobiles. The current trend for many applications is to reduce vehicle ...

A literature review of the springback of doubly curved developable sheet metal surfaces is presented in this paper. Related analyses, such as large curvature plastic bending and double curvature ...

"Springback is becoming more of a problem as we try to use high-strength materials in many applications," Dr. Komgrit said. "This method is a useful way to eliminate the springback of high ...
