Laser additive manufacturing enables economical production of complex lightweight structures. To realize the potential benefits technology in industrial applications, fatigue performance parts additively manufactured materials must be modelized. The aim this paper is to present a new modeling approach combining plasticity and damage, appropriate for as-built Laser-Powder Bed Fusion (LPBF) model...

although bearing capacity of footings on top of slopes under monotonic loadings have been investigated widely so far, safety and bearing capacity of these structures against repeated dynamic loads have not been considered well enough. in this paper, lower bound dynamic shakedown theorem in its numerical form has been employed to firstly obtain bearing capacity of strip footings on top of slopes...

A method to calculate the elastic shakedown limit of transportation systems (e.g. pavements and railways) supported by geogrid reinforced soils is presented. For first time, lower-bound theory combined with a strength-based simulation approach, resulting in rapid quantify benefit geogrids on limit. It allows decoupling stress generation calculations, meaning it straightforward implement, requir...
