His current job is as Full Professor in the field of Material Engineering at Engineering Faculty, Udayana University, Jimbaran, Bali, Indonesia. His research interest covers subjects such as, Biomedical Engineering, biosensor, biomaterial, waste recycle, failure analyses, advance ceramic, metallurgy, composite, renewable energy, and environmental friendly manufacturing.

Speech Title: Developing Fracture Toughness Mode II (KIIC) Testing for advance ceramic

Abstract: There are three methods of applying a force to enable a crack to propagate: Opening mode(Mide I) that is a tensile stress normal to the plane of the crack, Sliding mode (Mode II) that is a shear stress acting parallel to the plane of the crack and perpendicular to the crack front, and Tearing mode (Mode III) which is a shear stress acting parallel to the plane of the crack and parallel to the crack front. The fracture toughness mode II ( KIIC) measurement is introduced in this research. The material for the experiment was silicon nitride (Si3N4). An Asymmetric bending test was suggested to for in plane stress to occur. In fracture toughness mode I (KIC), the sharp notch can be used for measurement. Sharp notch cannot be used for KIIC because notch is not a crack, the R-curve for short and long crack is not the same and roughness of microstructure will affect the result of measurement. In this research the crack was created by using opposite roller precracking. The result for KIIC is 5.0 ± 0.27 MPam1/2, meanwhile KIC is 5.5 ± 0.20 MPam1/2

Speech Title: Magnetically Soft Microwires for Technical Applications

Abstract: Soft magnetic wires can present magnetic properties suitable for industrial applications such as the giant magnetoimpedance (GMI) effect or fast single domain wall propagation related to the magnetic bistability [1-2]. These properties can be observed either in crystalline or in amorphous magnetic wires, but amorphous magnetic wires present several advantages, such as superior mechanical properties, the absence of the microstructure defects (grain boundaries, crystalline texture, dislocations, point defects,…) [1,2] and therefore long and precise post-processing is not required. For these reasons, amorphous wires have attracted considerable attention since the 70-s [1-3]. Glass-coated magnetic microwires prepared using the Taylor-Ulitovsky technique with thin metallic nucleus (typically with diameters from 0.5 to 50 mm) covered by flexible, insulating and biocompatible glass are quite demanded for a great number of applications [1-4]. Generally Co-rich microwires present excellent magnetic softness. However, Co belongs to critical raw materials. Therefore Fe-based microwires are preferable for large scale applications.  But as-prepared Fe-rich microwires present generally much lower GMI effect of than Co-rich microwires. Recently we observed that the magnetic softness and GMI ratio of Fe-rich microwires can be improved by stress-annealing [5]. In this work we observed a remarkable improvement of domain wall (DW) mobility, DW velocity, giant magnetoimpedance (GMI) effect and magnetic softening at appropriate stress-annealing conditions. Beneficial effect of stress-annealing on GMI effect and DW dynamics is attributed to the induced transverse magnetic anisotropy. Consequently, stress annealing enabled us to design the magnetic anisotropy distribution beneficial for optimization of either GMI effect or DW dynamics
