AB  - This paper gives an overview of the development of a new software solution for project management, intended mainly to use in industrial environment. The main concern of the proposed solution is application in everyday engineering practice in various, mainly distributed industrial companies. Having this in mind, special care has been devoted to development of appropriate tools for tracking, storing and analysis of the information about the project, and in-time delivering to the right team members or other responsible persons. The proposed solution is Internet-based and uses LAMP/WAMP (Linux or Windows - Apache - MySQL - PHP) platform, because of its stability, versatility, open source technology and simple maintenance. Modular structure of the software makes it easy for customization according to client specific needs, with a very short implementation period. Its main advantages are simple usage, quick implementation, easy system maintenance, short training and only basic computer skills needed for operators.

AB  - The integrity of welded structures depends on the load-carrying capacities of their welded joints. Having in mind that welding process produces a large microstructural gradient through the weld, resulting in variation of mechanical properties, micromechanical analysis that correlates the local stresses and strains with fracture toughness seems to be appropriate to ensure integrity. In this paper, a micromechanical model for ductile fracture has been applied for assessment of the crack growth onset in the strength-mismatched welded joints of various widths. High-strength low-alloyed (HSLA) steel is used as the base metal in quenched and tempered condition. The flux-cored arc-welding process in shielding gas is used. Two different fillers are selected to obtain over- and undermatched weld metal. Precracked (single-edged notch bend - SENB) specimens are experimentally and numerically analysed in static conditions of external loading. Computations of the void volume fraction ahead of the crack tip are performed using the FE method. Volume fraction of non-metallic inclusions in the materials forming the joint was determined using the quantitative microstructural analysis. Based on the critical value, fc, determined on round tensile specimens, CTOD at ductile crack growth initiation on SENB specimens is determined. It has been found that the micromechanical model enables determination of the constraint effect induced by different widths of the welded joints at the onset of the crack growth in tested specimens.

AB  - In this paper the micromechanical approach to ductile fracture was applied in a study of constraint effect on crack growth initiation in mismatched welded joints. The single-edged notched bend specimens (precrack length a(0)/W=0.32) were experimentally and numerically analyzed. The coupled micromechanical model proposed by Gurson, Tvergaard and Needleman was used. Constraint effect was tested by varying widths of the welded joints (6, 12 and 18mm). High-strength low-alloyed (HSLA) steel was used as the base metal in a quenched and tempered condition. The flux-cored are-welding process in shielding gas was used. Two different fillers were selected to obtain over- and undermatched weld metal. The micromechanical parameters used in prediction of the crack growth initiation on precracked specimen were calibrated on a round smooth specimen. The difference in fracture behavior between over- and undermatched welded joints obtained in experimental results was followed by numerical computations of void volume fraction in front of the crack tip.
