Ultimate strength assessment of stiffened panels using Equivalent Single Layer approach under combined in-plane compression and shear

Teguh Putranto et al.

Summary: The Equivalent Single Layer (ESL) approach is extended to model the ultimate strength of stiffened panels under a combination of in-plane compression and shear. The modified ESL model effectively captures the effect of shear load on ultimate strength compared to a detailed 3D FEM model of stiffened panels.

Ultimate strength assessment of stiffened panel under uni-axial compression with non-linear equivalent single layer approach

Teguh Putranto et al.

Summary: Steel stiffened panels are commonly used in engineering design and construction, but the numerical modeling and analysis of 3D stiffened panels can be complex. A homogenization method has been developed to transform 3D stiffened panels into an Equivalent Single Layer (ESL) to study their mechanical behavior effectively.
