Velocity jump in the crack propagation induced on a semi-crystalline polymer sheet by constant-speed stretching
Takako Tomizawa, Ko Okumura
It has long been known for elastomers that the velocity of crack propagation jumps as a function of strain. On the other hand, such a jump has not been reported in the literature f…

Visco- and plasto-elastic fracture of nano-porous polymer sheets
Takako Tomizawa, Ko Okumura
We study the dependence of the fracture surface energy on the pulling velocity for nano-porous polypropylene (PP) sheets to find two components: the static and dynamic ones. We sho…
