Description:

To further our understanding of failure in thermoplastic-based composite rods, the mode Ⅰ-governed cohesive zone model parameter of a basalt fiber reinforced polypropylene composite rod is evaluated. The relations between stress and strain, the maximum normal traction and final separation displacement are examined using a transverse tensile test method. The measured traction is verified by three-dimensional finite element analysis of rod-shaped double cantilever beam specimens. The numerical results show the close relation between the crack length and cube root of compliance, and yields a representative value of the mode I-governed critical fracture energy.
