In the context of Industry 4.0, interest towards additive manufacturing processes is growing due to their numerous advantages, such as possibility prototype, reduction waste material, inferior time market, ad so on. particular, a promising technology Direct Laser Deposition, which uses focused laser beam melt powders there are deposited. opposition well-established powder-bed fusion technologie...

in order to lighten the prestressed concrete solid members, nowadays, it is possible to make use of the advantage of hpc (fc'>60 mpa) as well as replacing the solid section with a psc thin-walled section for certain members such as circular and box columns. using the strength theory of aci, a numerical procedure along with a computer program was developed for the analysis of such sections ...

In the treatment of posterior wall fractures of the acetabulum, a modified distal radius T-plate can be substituted for one third tubular spring plates for fixation of thin, small, or comminuted posterior wall fragments. This technique is described as well as a case series of 33 patients with various posterior wall acetabular fractures.

In this article, the results of a study on energy absorption characteristics of foam-filled thin-walled structures with finite element analysis have been presented. Four specimens of thin walled structures have been filled with uniform foam and three specimens have been filled with linear four-layered foam. Also, eight layers HLH (High-Low-High) and eight layers LHL (Low-High-Low) have been sim...

most geologic changes have a seismic response but sometimes this is expressed only in certain spectral ranges hidden within the broadband data. spectral decomposition is one of the methods which can be utilized to help interpreting such cases. there are several time-frequency methods including: short-time fourier transform (stft), continuous wavelet transform (cwt), wigner-ville distribution (w...

Abstract Twin-wall structures can be cooled both externally and internally, raising great potential for use in high-temperature applications. However, their increased geometric complexity imposes a range of failure mechanisms consideration design. The primary aim this study is to identify the nature such by constructing Bree type interaction diagrams idealized double-wall systems under cyclic t...
