Abstract: Abstract Constitutive equations are derived for a 1-D micropolar Timoshenko beam made of a web-core lattice material. First, a web-core unit cell is modeled by discrete classical constituents, i.e., the Euler–Bernoulli beam finite elements (FE).… read more here.

Abstract: Abstract T-joints in laser-welded web-core sandwich panels connect face-plates with web-plates. Rotational stiffness of the T-joints affects transverse shear stiffness of the panels. In this paper we describe the effect of geometric and material parameters… read more here.

DOI: 10.1016/j.ijsolstr.2019.04.026
Abstract: Abstract A 2-D micropolar equivalent single-layer (ESL), first-order shear deformation (FSDT) plate model for 3-D web-core sandwich panels is developed. First, a 3-D web-core unit cell is modeled by classical shell finite elements. A discrete-to-continuum… read more here.
