Sommario
Mediante la condizione di costanza dell'integrale della velocità di dissipazione specifica si decudono per via analitica e per una varietà di carichi mobili, progetti di minimo peso di una trave continua a due luci uguali perfettamente plastica e di tipo sandwich.
Summary
Minimum-weight designs of a perfectly plastic continuous sandwich beam with two equal spans are obtained analytically for a variety of movable loads, on the basis of the condition of constant integrated specific dissipation rate.
