It was very common for women to wear hats in the early 20th century. Most studies regarding millinery are limited to a discussion of style, while some focus on extended functions of millinery styles such as how they aid in social communication. In this study, we discuss the relationship between a woman's socioeconomic status and her hat-wearing behavior. This study covers the period from 1900 through the 1960s, when there was a sudden decline in hat-wearing behavior. We analyzed the changes in the number of people listed in various occupational categories in the U.S. Bureau of Statistics data for each decade. Careful observation of labor distribution statistics for the job market can yield valuable insights about women's hat-wearing behaviors. Fluctuations in the population of the lower class were significantly correlated with changes in millinery. We also identified time-sensitive periods in millinery style that coincided with the two World Wars.展开更多

Finite element analyses are performed for the flexural buckling of initially curved and twisted thin rods under simultaneous action of axial force and torque. Numerical examples demonstrate that the given formulae are correcte. Some numerical results are compared with existing analytical solutions and data obtained by commercial FE software. The convergence of the proposed curved element is better than that of elements in the commercial FE software. It is shown that good accuracy and convergency are achieved by solving three-dimensional problems.展开更多
