theoretical analysis and numerical simulation of GFRP specimens' defects detection using infrared thermal wave testing technology based on linear frequency modulation excitation was carried out in this paper. Based on the theory of heat transfer and material science, the heat transfer model of GFRP specimen was established and analyzed, and the heat transfer process excited by linear frequency modulation excitation heat flow was numerically simulated. through three-dimensional modeling and finite element analysis, the detection effect of different size defects under experimental conditions was analyzed. By calculating the temperature difference and contrast curve, the influence law of the defect diameter depth ratio on the detection effect was obtained, which can provide a certain reference for the detection test research.

IDS (Inter-Dendritic Solidification) is a thermodynamic-kinetic software package that simulates phase changes, compound formation/dissolution, and solute distribution during solidification of steels as well as during their cooling/heating process after solidification. the software package also simulates solid-state phase transformations related to the austenite decomposition process at temperatures below 900/600 degrees C, and calculates thermophysical material properties from the liquid state down to room temperature. these data are needed in other models, such as heat transfer and thermal stress models, whose reliability heavily depends on the input data. the software package also features a database for thermodynamic, kinetic and microstructure data, as well as for several material properties. Owing to the short calculation times, the IDS tool is suitable for online applications. this paper presents IDS and its modules withthe latest developments and validations, along with examples of modeling results.
