Seizure

Wirksame Wissenschaft und Forschunge. Several alternative representations of energy flux in the form of integrals over some finite region around the crack tip are presented and compared with a view toward implementation in finite element simulation studies.

Reliable crack arrest and impact fracture toughness data can only be obtained by evaluation procedures which take the dynamic effects into account, e.g. by utilizing the reduced dynamic effects crack arrest teat specimen or by applying the concept of impact response curves.

Some basic problems in stress wave dominated fracture,rocess, the speed of crack growth and the branching phenomenon. Also we examine critically the contention that there exists a unique relation which links instantaneous crack speed to the instantaneous stress intensity factor in brittle solid. That question hinges materially on limitations of current measurement techniques.

On the dynamic fracture of structural metals, data obtained by either direct optical measurements or numerical simulations of crack growth are presented. It is demonstrated that large errors in the velocity records caused by stress wave effects are a main source of uncertainty in the interpretation of experimental results.
