The proposed criterion is based on the plastic work dissipated in the structure as loading progresses and may be used for structures subject to a single load or a combination of multiple loads.
This paper presents an extension to this algorithm for topology design under multiple load cases of two/three-dimensional continuum structures.
To investigate complicated mechanobiological events at the cellular level, microdevices that are capable of delivering controlled and identical mechanical signals to multiple loading sites are of imperative need.
The results indicate that it is necessary to consider the combined effect of multiple loading in the fatigue analysis of long-span suspension bridges.
Some ideas regarding reversibility of the unloading process and elasticity of multiple loading unloading are also presented.
In practice, a structure is subjected to given loads and boundary conditions, and a multitude of stress and strain states may exist in the structure; hence, optimal construction of a laminate in a structure cannot be sought by considering only a limited number of stress resultants in the existence of multiple load cases.
The load model addresses spatial distribution of the load (e.g., concentrated load, distributed load, multiple load, etc)., speed of the load (e.g., constant speed, varying speed, etc)., trajectory of the load (e.g., straight line, curve, etc)., and magnitude of the load (e.g., constant load, impact load, sinusoidal load, varying load, and random load).
Therefore, the application of multiple loading conditions was considered to provide better results, particularly in the case of voided slabs: voided slabs are vulnerable to the shear strength deterioration because they use of less concrete in the slab web and therefore less concrete is available to resist shear.
A mechanical model of deep beam structure subjected to multiple loading is established, including analysis of roof support in the return airway of S1203 working face in the Yuwu coal mine, China.
The situation of multiple load conditions is considered.
