6005A-T6铝合金双轴肩搅拌摩擦焊接头的断裂行为

采用光学显微镜(OM)和扫描电子显微镜(SEM)对正常断裂和异常断裂的"之"形线进行研究,探讨了两类断裂中"之"形线的来源以及形成机理.双轴肩搅拌摩擦焊(BTFSW)正常断裂时"之"形线不是力学性能的薄弱区,抗拉强度可以达到母材的80％以上,"之"形线来源于原始对界面上的氧化膜;而异常断裂时"之"形线是力学性能的薄弱区,为未连接缺陷,强度仅为母材30％左右,由于焊接过程中搅拌头前方的待焊材料存在较大的横向拉伸应力,造成实际间隙超标,导致异常断裂.

钢板桩码头施工过程受力分析

运用大型有限元软件建立三维有限元模型,模拟钢板桩码头施工过程中板桩的桩身侧向位移、桩身土压力以及桩身弯矩的变化规律,从而了解施工过程中钢板桩的受力情况。研究结果表明：随着抛填施工的进行,板桩墙的侧向位移逐渐增大,呈两头小、中间大的侧移趋势;板桩墙侧土压力沿深度方向均呈缓慢的增大趋势,最大土压力为激活板桩墙及后侧回填土工序墙底部的152.1 kPa;板桩墙由于上端受拉杆约束、下端受土体嵌固作用,弯矩大体呈“S”。

Employability skills of maritime business graduates: industry perspectives

The maritime industry underpins international business and world trade. As to be expected, business management is critical for the maritime industry, requiring highly trained individuals and teams to lead the development, implementation and control of sound contemporary management practices. Maritime business degrees are developed by universities to meet such demand by providing graduates with sufficient skills for the onshore business-related roles. This empirical study conducted in Australia, USA and Canada, investigates current and future industry employability skills for maritime business graduates through focus groups, individual interviews and an online survey with senior managers in maritime organisations. This study found the important employability skills for maritime business graduates which include communication, problem solving, adaptability, self-management, team work, and digital literacy and technology. Demand for digital literacy and technology knowledge and skills have increased due to the maritime industry having a trend of moving towards digitalisation and automation. However, the survey findings revealed that a skills focus for maritime business graduates will not be the technology itself but the use and management of technology. In relation to future skills/knowledge required from maritime business degree graduates in 10 years’ time, communication and adaptability are recognised as being the most important. Employers expect that maritime business graduates should be able to adopt new technology and be competent in communication, and be more adaptable given the highly dynamic nature of the maritime industry. Moreover, they require graduates to be equipped with a higher level of computer skills, have a strong work ethic and multilingual skills.
