AB  - Problem statement: In structural analysis using finite element software, a number of finite
element equations affect the speed of calculation time. A reduced finite element model should be used
for analyzing structural responses to reduce the calculation time. Approach: This study presents the
analysis of transverse shear stiffness of truss-like core sandwich beam using the reduced finite element
model based on a unit cell approach. Two kinds of core topologies; an X-truss core and a bi-directional
X-truss core, were chosen to be analyzed. The presented reduced finite element model based on the
unit cell approach was compared in transverse shear stiffness with the conventional three-point loaded
beam approach. Results: Results showed that the unit cell approach could be used for analyzing the
transverse shear stiffness of truss-like core sandwich beam with a good correlative with the
conventional three-point loaded beam approach and a significantly reduced number of finite element
equations. Conclusion: The transverse shear stiffness of truss-like core sandwich beam can be
obtained from the reduced finite element model based on unit cell approach. This reduced finite
element model can be used to reduce the number of finite element equations; consequently, the speed
of calculation time is increased.
