Abstract: The concept of resilience is applicable to systems
with anticipated performances and subject to disturbances.
Understanding and quantifying resilience enable societies
to use resources efficiently for enhancing or maintaining the
performance of systems such as infrastructure. For example,
natural disasters as disturbances resulted in worldwide direct
damages of US$366 billion and 29,782 fatalities in 2011 alone.
Storms and floods accounted for up to 70% of the 302 natural
disasters worldwide, with earthquakes producing the greatest
number of fatalities. Managing these risks and others rationally
requires an appropriate definition of resilience and associated
metrics. This presentation provides a resilience definition that
meets a set of requirements with clear relationships to reliability
and risk as key relevant metrics. Such metrics provide a sound
basis for the development of effective decision- and policy-
making methods for multihazard environments for various
system types, including lifeline, environmental, financial, etc.,
systems. The presentation also examines recovery, with its
classifications based on level, spatial, and temporal
considerations. The economics of resilience is briefly
discussed.

Design for Additive Manufacturing: Opportunities and
Challenges

Abstract: Broadly speaking, the idea of design for additive xlvii
manufacturing (DFAM) is to explore new design spaces
to take advantage of the unique capabilities of AM processes.
With tremendous design freedom available, resulting device
designs can be complex geometrically, with complex material
and property distributions, that perform multiple functions.
At the same time, AM processes perform millions of
operations to fabricate a part. Is it any wonder that parts
exhibit more variability than in conventional manufacturing
processes? In this talk, I explore the opportunities and
challenges surrounding these issues of DFAM. Regarding
opportunities, I highlight two directions. First, I present
the idea of simultaneous design of a part, its material, and
its manufacturing process since these are intimately linked
in additive manufacturing. The fundamental need is
to integrate materials information, specifically process-
structure-property relationships, in order to determine
if desired spatial distributions of properties are feasible
given a material and a manufacturing process. Second,
I highlight the need for methods of robust and reliability
design to address process variabilities and enable part
qualification. Regarding challenges, several topics are
addressed, starting with the rapid changes in the AM industry.
Additionally, a core attribute of AM processes is that both the
part geometry and part material is fabricated simultaneously,
in contrast to conventional manufacturing processes, which
is the source of many challenges. The talk concludes with an
overview of commercial software offerings to support DFAM,
as well as standardization efforts that offer guidance to
designers.
