Indirect evidence for local heating comes from melted droplets on the fracture surface (Figure 8.7) or a sparking phenomenon at the moment of fracture. However, it is incorrect to deduce that shear bands in metallic glasses have a thermal origin or are essentially an adiabatic phenomenon, ...
Shear failure is mainly caused by shear force in combination with bending moment. The existence of shear force and diagonal cracking invalidates the plane section condition (Bernoulli’s hypothesis) and causes great difficulty in evaluating the stress and strain in the failure zone. Therefore, the ...
Numerical results for a number of sample problems and their comparison with analytical solutions have been presented for circular as well as for non-circular curved beams. Displacements, bending moment and torque for static loading with or without elastic foundation, as well as natural frequencies ...
A number of limitations exist in the models mentioned above, including inadequate consideration of key factors and simplified formulation derivations. Machine learning (ML) has rapidly developed in recent years, providing us with new means of solving complex problems. This method has been applied to ...
This warrants investigation to assess how design ratios (bending moment to shear force) influence structural integrity. Although several studies have explored the application of machine learning models, such as ANN and hybrid algorithms, there remains a gap in integrating advanced optimization techniques ...
An external magnetic field acts on the magnetic moment of a rigid particle surrounded by an elastomer and creates a moment of forces, which in the equilibrium can be compensated only by elastomer’s deformation see Fig. 1. Figure 1 Schematic representation of the shearing experiment in MAEs. (...
and column, all loads applied on the floor should be passed through the slab-column connection that creates a complex distribution of forces. Moment transfer phenomenon will also add to the existing complexity. Punching shear and ensuring that there is no punching failure, is an important option ...

where 𝐼=𝑏ℎ312I=bh312 is the moment of inertia of the beam section, E is the material elastic modulus of the beam, and L is the length of the upper parallel beam. Figure 6. Primary structure force analysis diagram of a parallel beam elastic element. The corner 𝜃1θ1 formed...
Find the power being transmitted and the torsional strain energy per metre length. If, in addition to this torque, a bending moment of 15 kN m together with an axial compressive force of 80 kN also acted upon the shaft, find the value of the equivalent stress in simple tension ...
