连续包覆型腔内应变分布的三维光塑性实验研究

STUDY OF THE STRAIN DISTRIBUTIONS IN THE DIE CHAMBER OF CONTINUOUS CLADDING BY THREE DIMENSIONAL PHOTOPLAS TICITY

以聚碳酸酯为模型材料, 首次采用三维光塑性方法对连续包覆型腔内金属流动过程进行了模拟实验研究,给出了稳态变形阶段型腔内的三维应变分布。分析了型腔内应变分布的特点。

Using polycarbonate as model material,three dimensional photoplasticity is employed to simulate the deformation of the metal in the die chamber of the continuous cladding process.The three dimensional strain distributions in the die chamber of continuous cladding in steady deformation stage are investigated.The features of the strain distributions are analyzed,and the flow pattern of the metal in the chamber is characterized.
