The Femme Fatale and the Exotic Queer within Shinya Tuskamoto\u27s Tetsuo: Gender as Narrative Tool within an Allegory for Post WWII Japan\u27s Industrialized Identity Crisis
No full textWithin Shinya Tsukamoto’s seminal independent horror masterpiece Tetsuo, the viewer’s perceptions of reality and the present are distorted within a temporally disjointed blend of horrific fantasy and banal existence; this instability reflects the vocal and subconscious critiques of historical ontological truths exhibited within the emergent transnational genres of Japanese cyberpunk and American Avant-pop ideologies of the late 1980’s. Author Takayuki Tatsumi uses Shinya Tsukamoto\u27s Tetsuo to illustrate the emergence of the Japanoid, a technologically driven fusion of American and Japanese post-war identity best understood as a manifestation of Donna Haraway\u27s socio-political cyborg. Tatsumi strongly advises avoiding interpretation through a queer lens, proposing that the use of “cyborg” and scrap iron serve as an analogy for the stratification and integration of disenfranchised post WWII Okinawan “scrap apaches.” However, Tetsuo’s prominent homoerotic elements cannot be ignored. Arguably, The film presents as blatantly non-heteronormative; to ignore queerness and instead focus solely on Tatsumi\u27s definition of identity ignores the meaning of masculinity in a patriarchal culture, rendering an incomplete (post)colonial reading. A queer reading clarifies Tsukamoto\u27s take on the contemporary disenfranchisement of the so-called Japanoid identity that Tatsumi embraces. Within Tetsuo, representation of woman as femme fatale and an overt queering of masculinity problematize the traditional heteronormative Japanese identity

Inexpensive Fracture Toughness Testing of Welded Steel
No full textIn a prior project, TNO has presented a low-cost way of finding fracture toughness of base materials for cleavage fracture. That method features a small-scale CTOD specimen, combined with simplified sensors, less fatigue pre-cracking, faster testing, and no need for a temperature chamber. This method has been extended to welds by considering the effect of pop-ins. This paper summarizes the prior method and the justifications for it before extending it to welded structures by introducing adjustments for pop-ins for small-scale specimens.Accepted Author ManuscriptShip Hydromechanics and StructuresBUS/TNO STAF
Numerical Study of Dynamic Behavior of a Self-supported Sheet Pile Wall
No full text地震時における自立式矢板護岸の動的変形挙動を把握するため，遠心模型実験および数値解析を実施した。数値解析においては，地震動が加わる前の矢板の初期拘束条件や，矢板・土要素間のモデル化の方法など，種々の条件を変化させ，解析条件の違いが解析結果に及ぼす影響について考察を行った。その結果，自立式矢板護岸の地震時挙動を精度良く予測するためには，地震動が加わる前の矢板の初期曲げモーメント分布に代表される，静的な応力状態を正確に再現することが必要不可欠であることが確認された。また，飽和砂地盤を対象とした場合，受働側の矢板・土要素間にジョイント要素を導入することで，解析精度が向上することがわかった。Physical model tests under centrifugal acceleration are conducted and results are compared with the one obtained by a finite element analysis. When the lateral movement of the sheet pile head is fixed during the self-weight analysis in simulation, that is the same condition as the model tests, computed bending moments due to consolidation agree with measured ones and also deflections after shaking are generally consistent with each other. While if the pile head is free in the self-weight analysis, computed bending moments and deformations disagree with measured ones. Thus, to simulate an existing sheet pile wall behavior during large earthquakes with accuracy required in practice, it is necessary to obtain in-situ bending moment profiles and input them as an initial condition.地震時における自立式矢板護岸の動的変形挙動を把握するため，遠心模型実験および数値解析を実施した。数値解析においては，地震動が加わる前の矢板の初期拘束条件や，矢板・土要素間のモデル化の方法など，種々の条件を変化させ，解析条件の違いが解析結果に及ぼす影響について考察を行った。その結果，自立式矢板護岸の地震時挙動を精度良く予測するためには，地震動が加わる前の矢板の初期曲げモーメント分布に代表される，静的な応力状態を正確に再現することが必要不可欠であることが確認された。また，飽和砂地盤を対象とした場合，受働側の矢板・土要素間にジョイント要素を導入することで，解析精度が向上することがわかった。Physical model tests under centrifugal acceleration are conducted and results are compared with the one obtained by a finite element analysis.
