摘要:Abstract(#br)The Equivalent Static Loads Method (ESLM) is an algorithm intended for dynamic response structural optimization. The algorithm attempts to solve a sequence of static response structural optimization problems approximating the original problem. It is argued in several...

摘要:... The basis of HASPs’ dynamic response calculation is equivalent to the orthotropic panel. There are mainly two methods to calculate the dynamic response of orthotropic panels. One is the modal superposition method, and this method is an accurate calculation; the other meth...

摘要:... The weakly coupled method is a powerful method to solve this design problem as it transforms the underlying dynamic response optimization problem into a static response optimization problem subject to multiple load cases. These load cases can be conveniently defined using the...

摘要:Abstract(#br)In this research, a new layout optimization method is developed to consider high cycle fatigue constraints which occur due to variable amplitude mechanical loading. Although fatigue is a very important property in terms of safety when designing mechanical components,...

摘要:... Both stacking angle sequence and topometry of the composite hood were optimized based on the equivalent static load method. After the optimization, the head injury criterion (HIC), deflection and weight were measured to evaluate the performance of the composite hood. The deve...

摘要:Abstract(#br)A novel method for nonlinear dynamic response topology optimization is proposed using the equivalent static loads (ESLs) method. The ESLs are the loads that generate the same response field of linear static analysis as that of nonlinear dynamic analysis at each time ...

摘要:Abstract(#br)In this paper, a method for the concurrent topology optimization of macrostructural material distribution and periodic microstructure under dynamic loading based on the equivalent static loads (ESLs) in the time domain is proposed. The sensitivity analysis of the max...

摘要:... The equivalent static load method is employed to transform the topology optimization of the nonlinear dynamic response of the system into a static one, and evaluated to adapt to the absolute nodal coordinate formulation by splitting the elastic deformations of the flexible co...

摘要:Abstract(#br)The forging process, which is the shaping of a workpiece using compressive loads, is a representative plastic manufacturing process and typically consists of a multi-step process with a preforming process. The workpiece shape is an important factor because it influen...

摘要:Abstract(#br)All loads in the real world act dynamically on structures. Since dynamic loads are extremely difficult to handle in analysis and design, static loads are utilized with dynamic factors. The dynamic factors are generally determined from design codes or experience. Ther...
