A Transformation-Induced Plasticity (TRIP) steel matrix reinforced with magnesium-partially stabilized zirconia (Mg-PSZ) particles depicts a superior energy absorbing capacity during deformation. In this research, the TRIP/TWIP material model already developed in the framework of the Düsseldorf Advanced Material Simulation Kit (DAMASK) is tuned for X8CrMnNi16-6-6 TRIP steel and 10% Mg-PSZ composite. A new method is explained to more accurately tune this material model by comparing the stress/strain, transformation, twinning, and dislocation glide obtained from simulations with respective experimental acoustic emission measurements. The optimized model with slight modification is assigned to the steel matrix in 10% Mg-PSZ composite material. In the simulation model, zirconia particles are assigned elastic properties with a perfect ceramic/matrix interface. Local deformation, transformation, and the twinning behavior of the steel matrix due to quasi-static tensile load were analyzed. The comparison of the simulation results with acoustic emission data shows good correlation and helps correlate acoustic events with physical attributes. The tuned material models are used to run full phase simulations using 2D Electron Backscatter Diffraction (EBSD) data from steel and 10% Mg-PSZ zirconia composites. Form these simulations, dislocation glide, martensitic transformation, stress evolution, and dislocation pinning in different stages of deformation are qualitatively discussed for the steel matrix and ceramic inclusions.

Addition of Sulfur to iron alloys improves the machinability of the components but reduces the formability. In this research, effect of varying Sulfur content from 0.008% to 0.03% in 16MnCr5 alloy steel on the formability of this steel grade by employing different formability tests is carried out. Tensile testing, transverse extrusion testing, expansion testing, and compression testing of normalized and non‐normalized samples is carried out to investigate the deformation behavior. Numerical simulation model is developed on commercial FEM software ABAQUS using realistic material data and load history to get information about the distribution and evolution of strains and stresses in the samples for different formability test conditions. The ABAQUS Simulations results are compared with experimental observations and are found to be in agreement with less than 7% error. The maximum local strain distribution of the transverse extrusion test is used as a boundary condition to simulate the phase field DAMASK numerical simulation model in this research. Through these phase field simulations, the interplay of MnS inclusions with Ferrite, Pearlite phases at strains just before failure are analyzed. The study provides a detailed insight into the factors responsible for difference in formability of 16MnCr5 alloy steel due to varying Sulfur content.

This paper presents a study of a piezoelectric energy harvesting circuit based on low-power-consumption synchronized switch technology. The proposed circuit includes a parallel synchronized switch harvesting on inductor interface circuit (P-SSHI) and a step-down DC-DC converter. The synchronized switch technology is applied to increase the conversion efficiency of the circuit. The DC-DC converter is used to accomplish the impedance matching for different loads. A low-power-consumption microcontroller and discrete components are used to build the P-SSHI interface circuit. The study starts with theoretical analysis and simulations of the P-SSHI interface circuit. Simulations and experiments were conducted to validate the theoretical analysis. The experimental results show that the maximum energy harvested by the system with a P-SSHI interface circuit is 231 μW, which is 2.89 times that of a system without the P-SSHI scheme. The power consumption of the P-SSHI interface circuit can be as low as 10.6 μW.
