Viscoplastic Characterization and Fatigue Modeling of Titanium Based Metal Matrix Composites

Viscoplastic characterization and fatigue modeling of titanium-based metal matrix composites was accomplished by combining a unified viscoplastic theory, a nonlinear micromechanics model, and a linear damage accumulation model. First. Ti 15-3 was characterized using the Bodner-Partom viscoplastic theory. A micromechanics model was then employed in a linear damage accumulation fatigue model to predict the fatigue behavior of titanium based composites. The viscoplastic behavior predictions of the micromechanics model were used to eliminate separately defined time dependent terms in the fatigue model. Also, a new linear damage accumulation model was developed from the fatigue behavior of the composite constituents. Finally, it was found that the microstresses in the 0 degree ply could be used to accurately predict the fatigue behavior of a laminate containing these plies

The Greatest Mother of the World

“The Greatest Mother in the World” was one of many posters issued during World War I to encourage support of the war. This poster was commissioned by the Red Cross from Alonzo Earl Foringer, or A. E. Foringer, in 1918. Foringer, an American painter, was a member of an important political family in Pennsylvania. Before the war the Red Cross was a small and insignificant organization based in the U.S.. During the war, they saved money and provided help to the warring nations in Europe. Once the U.S. entered the war, the Red Cross exploded with volunteers and funding from the government. WWI made the Red Cross into a global organization that was capable of helping people around the world. This poster shows a young woman in a Red Cross uniform. The woman has soft features and her eyes look upward as if praying as she holds a wounded soldier, on a stretcher, in her arms. This was to encourage the image the Red Cross wanted to present as being the greatest mother in the world. This popular poster was used many times throughout the war. This poster specifically also advertised the Red Cross Christmas Roll Call on Dec. 16-23, 1918. The armistice between the Allies and Germany was signed in November 1918. This armistice effectively ended the war, however, the Red Cross recognized that there would be a tremendous amount of work to do after the influenza pandemic had killed an estimated 21 million people. The decision to conduct a major membership drive for the Red Cross was made in November 1918. The goal of the Universal Membership Week was to enroll every American as a member. This goal was not achieved (American Library Association Archives, 2019). The poster was created and reproduced as a lithographic print at the time of it’s distribution.https://knowledge.e.southern.edu/wwiposters/1053/thumbnail.jp

Still the Greatest Mother

“Still the Greatest Mother” was one of many posters issued during World War I to encourage support of the war.This poster was commissioned by the Red Cross from Alonzo Earl Foringer, or A. E. Foringer, in 1920. Foringer, an American painter, was a member of an important political family in Pennsylvania. The poster was a reiteration of an earlier work by Foringer titled “The Greatest Mother”. Before the war the Red Cross was a small and insignificant organization based in the U.S.. During the war, they saved money and provided help to the warring nations in Europe. Once the U.S. entered the war, the Red Cross exploded with volunteers and funding from the government. WWI made the Red Cross into a global organization that was capable of helping people around the world. This poster was inspired by a Red Cross slogan created by a Princeton graduate, Courtland Smith. It was printed many times and became one of the most popular pieces of American visual propaganda during the war years. The poster was created and reproduced as a colored print at the time of it’s distribution.https://knowledge.e.southern.edu/wwiposters/1004/thumbnail.jp
