The compressive strength played the fundamental role in these types of applications. In present work, an attempt has been made to understand the effects of processing parameters on compressive strength of FDM made parts. The experimental plan has been designed using full factorial method with part ...
The effect of marine environment and carbon fibers reinforcement on compressive strength of the various design of PLA 3D-printed porous lattice structures doi:10.1007/s40964-025-01129-xAdditive manufacturing is one of the advanced manufacturing methods, and one of its techniques is fused filament ...
Their models demonstrate that lattice structures' stiffness and strength can be scaled with the cube of the relative density, assuming bending-dominated behaviour in open-cell structures. This scaling law has become a cornerstone in the design of lightweight structures, guiding the optimization of ...
This paper combines ultrasonic parameters recorded from P- and S- waves and effective porosity to estimate uniaxial compressive strength, σC, and intrinsic permeability, k - two of the most crucial physical parameters used in stone conservation studies. The ultrasonic parameters have been chosen beca...

This paper studied corrosion-inhibition and compressive-strength performances of Na2Cr2O7 (sodium dichromate) and C10H14N2Na2O8.2H2O (ethylenediaminetetraacetic disodium salt: EDTA-Na2) admixtures in steel-reinforced concrete immersed in NaCl and in H2SO4 corrosive environments. Electrochemical methods were...
As a kind of rock material, the elastic modulus and strength of cement mortar can be adjusted on a large scale. Based on the previous studies, this paper employs cement mortar as the rock-like material matrix. The material is made of water, 325 Portland cement and quartz sand with the ra...

These designs are 3D printed using ABS and PLA materials. Compression and impact tests are performed on a drop test rig and a compression test set-up. From the results, an optimal design is obtained that strikes a balance between compressive strength and impact absorption. In addition, a ...
Results showed that externally bonded CFRP composites considerably improved both the shear and flexural strengths of the beams. Notably speaking, the effectiveness of the CFRP composite material was inversely proportional to the concrete compressive strength. Significant improvement of the shear strength ...
