Experimental evaluation of the energy responsible for the crack advancing
Original language description
Many high performance ductile structures in civil engineering, automotive, aerospace and electrical industries are manufactured from high ductile thin wall materials. The mechanical behaviour of such materials is different from that of bulk (thick wall)materials. It is well known that measured value of fracture toughness strongly depends on many factors, namely geometry and type of loading. The existence of the plastic region in crack front is generally taken as a reason for dependence of fracture toughness on the body geometry. As appropriate determination of the fracture toughness evaluation of the energy responsible for fracture advancing can be considered. For such evaluation, the knowledge of several physical quantities is necessary: crack shapeand processing zone behavior, strain-stress field and plastic deformation. Combination of several experimental methods - computed tomography, Digital Image Correlation and strain gauge measurements were employed for this purpose.
