- Container ship are commonly employed in a variety of countries, particularly archipelagic countries like Indonesia. It is construction that very important to consider when building transverse watertight bulkhead because it serves as compartment divider the has leak and also strength ship. The purpose this research see if various modifications can bear working load. finite element method was s...

A topology optimization based approach is proposed to study the optimal configuration of stiffeners for the interior sound reduction. Since our design target is aimed at reducing the low frequency noise, a coupled acoustic-structural conservative system without damping effect is considered. Modal analysis method is used to evaluate the interior sound level for this coupled system. To formulate ...

methods retrospective cohort study of blunt trauma patients with rib fractures at a level i trauma center that had both a cxr and a ct chest. the ct finding of ≥ 3 additional fractures in patients with ≤ 3 rib fractures on cxr was considered clinically meaningful. student’s t-test and chi-square analysis were used for comparison. results we identified 499 patients with rib fractures: 93 (18.6%)...

This paper discusses the ultimate strength of composite plate girders with intermediate inclined stiffeners. The inclination angle stiffener, web opening size and span length are key factors influencing performance girder. study used LUSAS software to develop 20 non-linear finite element models using stiffener different angles, sizes lengths. have an 90°, 75°, 60°, 45° 30°. plates were divided ...

An earlier model for the study of rib cage mechanics was modified so that rib deformity in scoliosis could be better represented. The rigid ribs of that model were replaced by five-segment deformable ribs. Literature data on cadaver rib mechanical behavior were used to assign stiffnesses to the new individual model ribs so that experimental and model rib deflections agreed. Shear and tension/co...

OBJECTIVE Rib fractures are the most common injuries resulting from blunt chest trauma. The sensitivity of chest X-rays in showing the rib fractures is limited particularly in those involving the cartilage part of the rib. We investigated the possible rib fractures, those overlooked on chest X-rays, with the use of ultrasonography in minor blunt chest trauma. METHODS A total of 37 patients, w...
