Test of Fracture Toughness of Laser-Welded Joints Made of Duplex 2205 Steel SOLTYSIAK Robert1,a 1 University of Technology and Life Sciences, Faculty of Mechanical Engineering, Prof.
The above studies are particularly essential if they concern relatively new construction materials, and even more so if the materials are joined by use of relatively new welding techniques [8].
Second generation materials had much better weldability which was achieved e.g. by adding nitrogen as an alloying element.
Fracture toughness tests were carried out in the accredited Department Materials and Structure Laboratory on an INSTRON 8501 hydraulic fatigue testing machine.

Failure response and degradation of material properties were implemented using a progressive model, which is incorporated in ABAQUS USDFLD subroutine.
To perform a progressive failure analysis of composite materials, it is essential that the failure mode (i.e. fibre failure, matrix failure, etc.) be evaluated so that the appropriate material properties can be degraded accordingly.
Material strengths for HTA/6376 are shown in Table 3.The degradation rules used in USDFLD is shown in Table 4.

Magnesium and its alloys will represent a new class of degradable implant materials in orthopedic surgery.
Materials and Methods High purity magnesium (99.99%) was used in this study, the material was cut into 20 ×25 × 2mm slices.
For both materials, the O.D values deceased with increase of the contact time to blood.
High pure magnesium is appropriate for being degradable implant materials in orthopedic surgery.
