This work utilizes the commercial finite element software ABAQUS to investigate the factors influencing the mechanical behavior of tantalum carbide (TaC)-based/graphite fibrous monolithic ceramics (FMCs), such as core/shell volume ratio and fiber orientation. The good compliance between experimental and simulated results demonstrates the suitability of the finite element software ABAQUS for exploring mechanical properties in FMCs. According to the results, it was observed that the bending strength of TaC-based/graphite FMC decreased with the change in fiber orientation from 0° to 90°. The displacement amount in the core/shell volume ratio of 75/25 ( C75S25) sample with a fiber orientation of 90° was maximum (with a value of 0.0524 mm), indicating that crack propagation occurred later. Therefore, the sample exhibited better resistance to failure. Generally, C75S25 specimens started to crack later than the core/shell volume ratio of 65/35 ( C65S35) in both fiber orientations and released more energy during crack initiation. Additionally, when the 0°-fiber-oriented specimen failed, more energy was released than the [90°] sample with the same core/shell volume ratio.

본 논문은 Contour Crafting(CC) 프로세스의 압출과 적층 단계에서 물질 흐름의 형태를 연구하기 위한 실험과 모델링을 보여준다. 특히, 실험재료로써 진흙을 이용한 압출과 적층 메커니즘을 이해하기 위하여 기초적인 유한성분분석(FEA)을 실행하였다. FEA 시뮬레이션을 이용한, CC의 성능에 있어서 압출구멍의 기하학적인 효과에 대한 분명하고 기본적인 이해를 하게 되었다. 네모난 형상이 원하는 외부 표면특성을 만드는 것뿐만 아니라, 그리고 층간에
