Abstract The prediction of crack initiation and propagation in ductile failure processes are challenging tasks for the design fabrication metallic materials structures on a large scale. Numerical aspects dictate sub-optimal calibration plasticity- fracture-related parameters number material properties. These enter system partial differential equations as forward model. Thus, an accurate estimat...

Study about Fracture Mechanics and the root cause of fracture in order to estimates lifetime for Mechanical parts in designing process and manufacturing have tremendous role in this realm. Stress intensity factor comes into design which not only is dependent to geometry also extremely to load condition; for instance, it is important in failure processes (brittle and ductile Materials) or to pre...

OBJECTIVES This study evaluated the impact and flexural strength and analyzed the fracture behavior of acrylic resins. METHODS Eighteen rectangular specimens were fabricated of Lucitone 550, QC 20 (both unreinforced acrylic resins), Impact 1500 (extra strength impact), Impact 2000 (high impact) according to the manufacturers' instructions. The impact strength was evaluated in notched specimen...
