| Summary: | The utilization of composite materials as structural material is increasing massively in
various sector. Increasing of needs in various sector push the further research and
development in composites materials to achieve the better performance. One type of joint
commonly is used as the composites joint is single-lap bolted joint. Further research related
to single-lap bolted, especially related to maximum joint strength (bearing) and failure
mechanism(bearing), is needed to achieve the better performance.
This research will conduct joint simulation with uniaxial tensile load by varying 3
parameters with total 16 joints variant. Varies is conducted to evaluate the influence each of
parameter to its performance. The model is built in continuum shell mode and evaluated using
Hashin failure criteria. The results will be compared with the experiment results that is
conducted in the previous research.
The simulation’s results show the consistent results compared with experiment results
in the previous study. Two failure mode, net-tension and bearing, occur in all joint variants.
Maximum joint strength from the simulation result show the varying values and the influence
each parameter regarding joint’s performance is concluded successfully. |
