Workshop on the Limits of Strength in Practice and Theory; Berkeley, CA; March 28-29, 2008

技术：这次计划举行的为期两天的研讨会有以下目标：(1)确定、分析和讨论理想材料强度的理论、实验观察和技术开发方面的最新进展。特别是，演讲和讨论将回顾最近发现的“胶金属”的迷人特性，它似乎获得了理想的整体强度，并通过无位错机制变形。(2)认识和讨论理想强度在许多新的和常见的行为模式中的作用，包括纳米压痕硬度、相变诱导塑性、结构材料的强度/韧性极限和冲击载荷下的行为。会议将于2008年3月28日至29日在加州大学伯克利分校校园举行。这些日期将与斯普林夫人在旧金山的会议结束时间重叠，以确保最大限度的参与。研讨会的主题将包括(但不一定限于)以下内容：1.理想强度的含义及其在力学行为中的作用根据第一原理计算理想强度。理想强度在纳米压痕中的作用。理想的散装强度：树胶金属及其可能的近亲。理想力量在卵裂中的作用。理想强度下的相变：应力诱导相变。理想强度在冲击中的作用：“机械熔化”。非技术性：研讨会将聚集一些对理想强度材料有重叠兴趣的研究人员，在一个适宜的环境中，这将促进讨论、辩论和启动长期合作。它还旨在鼓励年轻研究人员和代表性不足的群体成员参与这一令人兴奋的机械行为新领域。这些活动既有科学价值，也有技术价值。从科学上讲，这次研讨会将聚焦于力学行为的一个重要新领域。它将有助于交流当前研究的状况，激发讨论和新的研究想法，并建立有用的合作。从技术上讲，会议的讨论应该为如何在创造新材料方面利用力量的极限提供新的见解。研讨会的更广泛影响还将来自它应该鼓励的想法和它应该产生的合作。国际和平协会打算积极鼓励代表人数不足的少数群体参加，并已预留旅费，以鼓励和支持这类活动。PI预计，我们总出席人数的大约25%将是妇女，并将努力寻找对这一领域感兴趣的其他代表性不足的少数群体。将通过向该领域的研究人员发送电子邮件、征集合适的名称以及在现有技术协会的网站上宣布讲习班的方式来了解讲习班。

TECHNICAL: This planned two-day symposium has the following objectives: (1) To identify, analyze, and discuss the recent advances in the theory, experimental observation and technological exploitation of the ideal strength of materials. In particular, talks and discussions will review the fascinating properties of the recently discovered "Gum metal" that appears to attain ideal strength in bulk, and deform by a dislocation-free mechanism. (2) To recognize and discuss the role of ideal strength in a number of both new and familiar modes of behavior, including nano-indentation hardness, transformation-induced plasticity, strength/toughness limits on structural materials and behavior under shock loading. The conference will be held on March 28-29, 2008 at the campus of UC Berkeley. These dates are set to overlap the end of the MRS Spring Meeting in San Francisco to ensure maximum participation. The topics the symposium will cover will include (but will not necessarily be limited to) the following:1. The meaning of ideal strength and its role in mechanical behavior.2. The computation of ideal strength from first principles.3. The role of ideal strength in nano-indentation.4. Ideal strength in bulk: Gum metal and its possible cousins.5. The role of ideal strength in cleavage.6. Phase transformation at ideal strength: "stress-induced" transformation.7. The role of ideal strength in impact: "mechanical melting".NON-TECHNICAL: The workshop will bring together a number of researchers with overlapping interests in the ideal strength of materials in a congenial environment that will facilitate discussion, debate and the initiation of long-term collaborations. It is also aimed at encouraging the participation of young researchers and members of underrepresented groups in this new and exciting field of mechanical behavior. The activities have both scientific and technological merit. Scientifically, the symposium will focus on an important new area of mechanical behavior. It will serve to communicate the status of current research, stimulate discussion and new research ideas, and establish useful collaborations. Technologically, the conference discussions should provide new insight into how the limits of strength may be exploited in the creation of new materials. The broader impact of the symposium will also come from the ideas that it should stimulate and the collaborations it should generate. PI intend to actively encourage the attendance of underrepresented minorities, and have reserved travel funds to encourage and support such attendance. PI anticipates that approximately 25% of our total attendance will be women, and will seek to identify other underrepresented minorities that are interested in this area. Awareness of the workshop will be achieved through emails to researchers involved in the field, solicitation of suitable names, and announcement of workshop on available technical societies' websites.
