A LINEARIZED TIMOSHENKO BEAM THEORY IN FINITE DISPLACEMENTS
Doboku Gakkai Ronbunshu, 1985 A linearized finite displacement theory of the Timoshenko beam is formulated as the counterpart to so-called beam-column theory of the Bernoulli-Euler beam. The corresponding stiffness equation is derived in a useful form for practical applications. Both theory and stiffness equation result in the same buckling load as the Engesser formula which has ...

Advanced Intelligent Systems, Volume 8, Issue 2, February 2026.This review explores how shape‐changing structures—origami, bistable, and laminate structures—enable multifunctionality in soft robotics and metamaterials. Starting from structural design, it examines core principles, real‐world applications, and ongoing challenges.

Effective Material Stiffness in Curved Actuators
Advanced Intelligent Systems, Volume 8, Issue 2, February 2026.A new actuator effective material stiffness measurement method is created. It produces a new metric called shape actuation modulus with the potential to help design actuators. This method shows that the smaller the curvature of hinge‐shaped actuators, the stiffer they are.

ON “A CHECK ON THE ACCURACY OF TIMOSHENKO'S BEAM THEORY” [PDF]
Journal of Sound and Vibration, 2002 In a recent article, Rneton (1) presented a comparison between the standing wave natural frequency predictions of Timoshenko beam theory (TBT) for a long beam of thin rectangular cross-section, when the flexural mode is sinusoidal in the axial co-ordinate x, and those of a plane stress elastodynamic solution; the latter may be regarded as the exact ...
