Approaches to the Determination of the Working Area of Parallel Robots and the Analysis of Their Geometric Characteristics
Dmitry MALYSHEV, Mikhail POSYPKIN, Larisa RYBAK & Alexander USOV
The article presents and experimentally confirms two approaches to the problem of determining the working area of parallel robots using the example of a planar robot DexTAR with two degrees of freedom. The proposed approaches are based on the use of constraint equations of coordinates. In the first approach, the original kinematic equations of coordinates in the six-dimensional space (two coordinates describing the position of the output link and four coordinates – the rotation angles...
Multi-criteria analysis on spatial data of the landscape
Paweł JAROSZ, Piotr ŁABĘDŹ & Paweł OZIMEKSolution of the plane contact problem between a finite-thickness laterally graded solid and a rigid stamp of an arbitrary tip-profile
O. Arslan
A singular integral equation (SIE) approach and a finite element method are developed for the solution of the frictional sliding contact problem between a finite-thickness laterally graded solid and a rigid stamp of an arbitrary tip-shape considering the plane strain assumption. An exponential shear modulus variation is introduced through the lateral direction. The field variables are obtained applying the Fourier transformation techniques on the governing partial differential equations. A surface displacement gradient is then utilized...
Experimental and Analytical Investigation of Point Fixed Corrugated Metal Sheets Subjected to Blast Loading
Kai FISCHER, Alexander STOLZ & Christoph ROLLERResponse Surfaces in the Numerical Homogenization of Non-Linear Porous Materials
Witold BELUCH & Marcin HATŁAS
The paper deals with the numerical homogenization of structures made of non-linear porous material. Material non-linearity causes a significant increase in computational costs for numerical homogenization procedure. An application of the response surface methodology allows a significant reduction of the computational effort providing good approximation precision. Finite element method commercial software is employed to solve the boundary-value problem in both scales. Due to the significant reduction in computing time, the proposed attitude may be applied...

T. BOBINSKI, G. SOBIERAJ, M. PSARSKI, G. CELICHOWSKI & J. ROKICKITheoretical and Numerical Analyses of an Aluminium-Concrete Composite Beam with Channel Shear Connectors
Łukasz POLUS & Maciej SZUMIGAŁA
This paper presents a numerical simulation and a theoretical investigation of an aluminiumconcrete composite (ACC) beam subjected to bending. ACC structures are similar to steel-concrete composite (SCC) structures. However, their girders are made of aluminium instead of steel. The use of ACC structures is limited because of the lack of relevant design rules. Due to this fact the authors suggest applying the theory for SCC structures to ACC structures. In this paper, the methods for...
Numerical Modelling of Post-Ground Subsystem in Road Safety Barrier Crash Tests
Marian KLASZTORNY, Daniel Bronislaw NYCZ, Pawel DZIEWULSKI, Roman GIELETA, Michal STANKIEWICZ & Karol ZIELONKA
A new analytical algorithm for determining the elastoplastic parameters for soft, medium and hard plastic cohesive soils, corresponding to *MAT_005_SOIL_AND_FOAM material model available LS-Dyna FE code, was formulated. The numerical modelling of the post-soil subsystem, applicable in the modelling of road safety barrier crash tests using this material model of the roadside dehydrated ground, was developed. The methodology was presented on the example of a Sigma-100 steel post partly driven into the soil and subjected...
