This study focuses on lightweight optimum design of head pressure shell of an autonomous
underwater vehicle (AUV) with reliability requirements. The grid sandwich structure is …

This paper presents research on the effect of riveting process parameters on residual
stresses, clamping stresses and clamping force in thin sheet riveted joints, as well as the …

The implementation methods of finite element analysis (FEA) have remained essentially
unchanged since the inception of FEA in the 1960s. Alterations of any of the input or design …

Architected lattice materials, realized through artificial micro‐structuring, have drawn
tremendous attention lately due to their enhanced mechanical performances in …

While several theoretical and experimental studies for cracks in piping exist, most pertain to
pipelines, equipment, or fittings under pressure conditions or under stress corrosion …

If a conventional material is compressed in one direction, it tries to expand in the other two
perpendicular directions and vice versa, indicating a positive Poisson's ratio. Recently …

This paper presents a modified variational method for the dynamic analysis of functionally
graded piezoelectric (FGPM) deep curved beams with porosity (FGPP beam) resting on an …

Although the wave finite-element method (WFEM) is an efficient numerical technique to
analyze wave propagation characteristics and forced response of waveguides at medium …

Lightweight meta-structures can reveal combinations of properties that do not occur in
conventional structures. In this paper, a 2D bi-material unit cell is proposed based on a re …

A research subject in structural engineering is the problem of vibration under a loading
object. The two-dimensional (2D) model of a structure under loading is an example. In …
