中文摘要：
为了研究几何参数对T型构件局部加载过程的影响,应用主应力法建立了充分考虑圆角半径、拔模斜度的新模型。实验和数值模拟结果验证表明新数学模型的结果更接近于实验和数值模拟值;拔模斜度的影响可以忽略;圆角半径的影响显著,特别是在圆角半径和筋宽的比率小于0.75的情况下更为显著。
英文摘要：
In order to study influences of geometric parameters on the T-shaped components local loading process, a new mathematical model considering the fillet radius and draft angle was established by using the slab method. The results obtained by the mathematical model agree with the data form experiment and numerical simulation, and the results are closer to the experimental and simulation results. The influence of draft angle may be neglected under the forming conditions used. The influence of fillet radius is notable, especially in the case that the ratio of fillet radius to rib width is less than 0.75.
