We consider a soft elastic matrix that contains particulate inclusions and is bounded by a rigid wall, e.g., the substrate. Such a situation arises in elastic composite materials. They may serve as soft actuators when forces are imposed on or induced between the embedded particles. We investigate how the presence of the rigid wall affects the interactions between the inclusions. First, for no-s...

The article describes the actual work’s numerical analysis for unit joining walls to bottom of vertical cylindrical tank 50 thousand m 3 . Having analyzed relevant stress-strain state tanks different types finite element model. Research carried out with a wall on rigid base. Features should include effect various loads: static, dynamic, cyclic, corresponding normal operation. load pressure liqu...

The recent re-assessment of the seismic hazard in Europe led for many regions of low to moderate seismicity to an increase in the seismic demand. As a consequence, several modern unreinforced masonry (URM) buildings, constructed with reinforced concrete (RC) slabs that provide an efficient rigid diaphragm action, no longer satisfy the seismic design check and have been retrofitted by adding or ...

The chamber configuration of an asymmetric, fixed-detached Oscillating Water Column (OWC) device was investigated theoretically to analyze its effects on hydrodynamic performance. Two-dimensional linear wave theory used, and the solutions for associated radiation scattering boundary value problems (BVPs) were derived through matched eigenfunction expansion method (EEM) element (BEM). results ef...

It is known that the distribution of active earth pressure against a translating rigid wall is not triangular but nonlinear, owing to arching effects in the backfill. In the present paper, a new formulation is proposed for calculating the active earth pressure on a rigid retaining wall undergoing horizontal translation. It takes into account the arching effects that occur in the backfill (or re...

The timber structural members of a seven-story building from the end 18th century were evaluated following procedure based on previous research works. structure consisted timber-framed brick walls and heavy floors with mortar filling. Non-destructive measurements taken in 13 sampling areas framed walls. Detailed at least 3 pieces each sample (stress wave Time-of-Flight probing tests). Mean dens...

The effects of elastic cavity walls on noise generation at transonic speed are investigated for the generic M219 cavity. flow is simulated with Spalart–Allmaras (SA) improved delayed detached-eddy simulation (IDDES) turbulence model in combination a wall function. structural analysis software uses modal formulation. first 50 normal mode shapes included simulation, spanning frequencies 468–2280 ...
