..., the cantilever structure detection unit is analyzed by numerical simulation using ABAQUS, and the sensor results are calibrated by simulation with modulus change. The modulus change of HTPB propellant aging process is detected by structural design, the factors affecting the measuring range of the cantilever...

... and applied micro strain. Design/methodology/approach This work has reported the numerical simulation of LPGS transmission spectrum behavior characteristics under the strain and temperature effects by using OptiGrating simulation software. The sensor fabrication material is silica-doped germanium...
