Dynamic multidimensional pressure deformation in the waist-abdomen region of young women

The measurement of dynamic deformation and pressure distribution of the human body is crucial for advancements in 3D body measurement, modeling, and the optimization of clothing patternmaking for both fit and comfort This study focuses on assessing the dynamic changes in pressure and deformation of the waist-abdomen region during posture transitions in young women wearing tight-fitting pants of different sizes and compared the dynamic deformability of real human body and virtual simulated models. Clothing pressure was measured in both standing and sitting postures, while 3D models of the waist-abdomen region were generated using 3D body scanning to capture body deformation patterns. The research examined the relationship between pressure distribution, circumference, and volume, along with their dynamic variations under different levels of pressure. A novel under-clothing bump grid method was introduced to measure and analyze the horizontal and vertical skin deformation of the waist-abdomen. A dynamic virtual human body model was constructed to compare and analyze its dynamic deformation. The findings revealed that clothing pressure distribution on the waist-abdomen is closely related to the physiological morphology of the body. Notably, the skin’s vertical deformations are more significant when sitting, with clothing pressure playing a significant role in the elastic deformation of the waist-abdomen. Additionally, the changes in circumference and volume follow a consistent pattern. This research offers novel insights for optimizing clothing design, enhancing the functional design and comfort design, and contributes to improving the body and clothing simulation.
