高速破坏的PMMA断裂表面形态与裂纹速度的相依关系
Dependece of Fracture Surface Morphology on Velocities in Fast Fracture of PMMA
【摘要】 利用超声波断口图和扫描电镜建立了有机玻璃快速破坏时断裂表面形态与主裂纹速度间的直接联系,提出了“能核”与“能核爆破”模式,并用此对断裂表面微观形态的特征和形成机理进行了解释。
【Abstract】 The direct relation between fracture surface morphology and crack velocities in fast fracture of PMMAare obtained by Ulreasonic fractography and SEM. Two medels of "Energy nuclei"and "Energy nuclei exploding"aresuggested and the characterization and formation mechanism of micro-morphology on fracture surface are interpretedby using them.
