The investigation of additive manufacturing and moldable materials to produce railway ballast grain analogs	2022	16	.pdf	application/pdf	6702	419	51	Specimens were made from railway ballast materials, three groups of moldable materials (materials used in the construction industry, thermosetting polymers, and certain low-strength materials) and additively manufactured polymers. The mechanical properties of polymers differ significantly from the properties of railway ballast materials, because their failure mode is large plastic deformation.	cache/fis-3210.pdf	txt/fis-3210.txt
