Beam elements have played a very important role in modeling mechanical engineering structures. Curved beams are known to be more efficient in transfer of loads than straight beams. The transfer in the curved beam is affected by means of bending, shear and membrane action. This is particularly important in studying initially curved beams. The aim of this project is to improve the use and flexibility...
Due to their high corrosion and chemical resistance, glass fiber reinforced plastic (GFRP) materials are increasingly being used in the construction of industrial chimneys. In this paper, the finite element model of a 60 m high GFRP chimney with the diameter of 3 m is established using finite element software ANSYS. The cylindric chimney, steel supporting frames and the two anchor cables are meshed...
A quantitative assessment of femur stress under compression and bending condition is essential for the understanding of failure mechanisms and providing guidance for the design and operation of femur replacement. The stress distribution of femur under bending moment and compressive load is simulated using finite element method (FEM) in this paper. A two-dimensional FEM model is established according...
With the trend towards high performance, portability and low cost for electronic products, the packaging density in microsystem has become higher and the components have tended to be minimal. Flip-chip technology is superior because of its high packaging density and speed signal processing. There is an increasing interest in using electrically conductive adhesives as the interconnection material in...
This paper discusses challenges for multi-scale Finite Element (FE) modeling in microelectronics. Its miniaturization and multi-scale nature is an enabler for in Healthcare and Well-being markets. Function integration and miniaturization enable microelectronic products having functionalities such as rollable display (Figure 1), wireless connectivity & GPS, beaming, illumination systems, body health...
This paper describes the nonlinear finite elements analysis (FEA) of soft fingertips for robotic hands in contact conditions. The purpose is to test the reliability of FEA when designing fingertips with differentiated layer design, that is the adoption of a single elastic material, dividing the overall thickness of the pad into layers with different structural design (e.g. a continuous skin layer...
This study demonstrates a finite element method for simulating the behavior of nanoindentation of copper nanowires and estimates their mechanical properties. The simulation results reveal that using well-known Oliver-Pharr theory, generally applied for materials with semi-infinite half-space, yields an underestimate of the elastic modulus of the wire materials. Moreover, the size of the indenter tip...
