Quasi-static and high strain rate compressive experiments on the vinyl ester resin casting were carried out by using a material universal testing machine and Hopkinson bar, and the behaviors of compressive instability and fracture of the resin casting at different strain rates were investigated. 利用电子万能试验机和分离式Hopkinson压杆研究了乙烯基酯树脂浇铸体在准静态和高应变率下的压缩特性,考察了试样压缩失稳和破坏的形貌。
