Study on the dynamic propagation and numerical simulation of mode Ⅰ and mixed mode Ⅰ-Ⅱ cracks in PMMA specimens with unilateral semicircular holes

Study on the dynamic propagation and numerical simulation of mode Ⅰ and mixed mode Ⅰ-Ⅱ cracks in PMMA specimens with unilateral semicircular holes

A new approach is provided to study the growth problems of mode Ⅰ and mode Ⅰ-Ⅱ mixed cracks, Split Hopkinson Pressure Bar(SHPB) is used to impact the PMMA USH(Unilateral semicircular hole) specimen containing precast crack.Results of mode Ⅰ cracks and mode Ⅰ-Ⅱ mixed cracks are obtained.At the same t...
