Mech. VL - 14 IS - 1 SE - Research Article DO - 10.15625/0866-7136/10225 UR - https://vjs.ac.vn/index.php/vjmech/article/view/10225 SP - 24-30 AB - <p>In this work comparisons are made between lower bound obtaining in [3], stronger and lower bound by The-Sawczuk. Finally the optimal problem is considered, namely that it must be chosen f<sub>i1</sub>(t) f<sub>i2</sub> (x<sub>k</sub>), for which a lower bound displacement is maximized.</p> ER -
