Cellular thin-shell structures are widely applied in ultralightweight designs due to their high bearing capacity and strength-to-weight ratio.In this paper,a full-scale isogeometric topology optimization(ITO)method based on Kirchhoff-Love shells for designing cellular tshin-shell structures with excellent damage tolerance ability is proposed.This method utilizes high-order continuous nonuniform rational B-splines(NURBS)as basis functions for Kirchhoff-Love shell elements.The geometric and analysis models of thin shells are unified by isogeometric analysis(IGA)to avoid geometric approximation error and improve computational accuracy.The topological configurations of thin-shell structures are described by constructing the effective density field on the controlmesh.Local volume constraints are imposed in the proximity of each control point to obtain bone-like cellular structures.To facilitate numerical implementation,the p-norm function is used to aggregate local volume constraints into an equivalent global constraint.Several numerical examples are provided to demonstrate the effectiveness of the proposed method.After simulation and comparative analysis,the results indicate that the cellular thin-shell structures optimized by the proposed method exhibit great load-carrying behavior and high damage robustness. 展开更多

This paper scrutinizes the differences in the conceptualization of love between Korean and American women.Grounded in an analysis of literary figures,Brett and Kim Ji-young,the study unravels the intricate interplay of cultural,historical,and societal forces shaping these perspectives.The contrasting landscapes of the United States,driven by ideals of freedom and individualism,and Korea,entrenched in Confucian values and collectivism,serve as crucibles for forming women’s roles,self-perception,and societal expectations.The examination extends to communication styles,illuminating the directness of American expression versus Korea’s reliance on formalism.Through this exploration,the paper illustrates the profound impact of cultural contexts on the intricate tapestry of love,offering a nuanced understanding of divergent viewpoints within a global context. 展开更多

Ernest Hemingway,the famous American writer,was one of the representatives of "the lost generation". He was good at depicting the life and the inner world of "the lost generation" ,especially the youth. A Farewell to Arms is one of his masterpieces. Because of the similarities between the hero and Hemingway himself,many critics regard it as an autobiographical novel. The novel develops with the themes of war and love,exposing the brutality and absurdity of World War I,and the unforgettable pain it caused. At the same time,Hemingway extolled beautiful and unselfish love. In an age filled with war and chaos,pure love served as a beacon in the darkness,bringing hope,comfort and courage to people. 展开更多

Anna Karenina and The Scarlet Letter are written by the Russian writer Leo Troels and USA novelist Nathaniel Hawthorne respectively.Both of them are masterpieces in the history of the world literature.The two masterpieces account for two different love stories happened in different background respectively.If you compare the heroine of the two classics- Anna Karenina's and Hester Prynne' s fate,we will find that the two have many similarities.They have a similar experience- they had to get married for getting married and then they fell in love again for seeking true love after they have married,finally they paid a heavy price for their extramarital love.However,Due to their different demands and understanding about love as well as different resistance form to protect their love,their ending is also quite different..This thesis mainly analyzes the causes of the fate of Anna and Hester respectively.This analysis is the combination of subjective and objective through social,life and spirit field,in order to achieve the dialectical unity both subjective and objective,the dialectical unity of personality and common. 展开更多
