U 型缺口小冲杆试验评价材料的各向异性
Evaluation of Anisotropy Material by Small Punch Test with U-shaped Notch
摘要
Abstract
This paper focused on the small punch test( SPT) at various temperatures,using specimens with a U-shaped notch.The standard specimens were fabricated from the anisotropy material along axial,cir-cumferential and radial directions, respectively, to study the mechanical properties.The ductile -brittle transition temperature TSP of the SPT can be determined by the small punch energy variation with tempera-ture.The test results indicated that SPT with notched specimens is competent to reveal the difference among the three directions in SPT transition temperature,as well as the difference in upper plateau frac-ture energy.It was therefore concluded that SPT using specimens with a U-shaped notch,is useful and effective to evaluate the mechanical properties of anisotropic material,combined with common SPT( with-out notched specimens) .关键词
